-**NOTE: THIS MANUAL IS WORK IN PROGRESS**
-
-Overview
---------
-
-Mongoose is small and easy to use web server. It is self-contained, and does
-not require any external software to run.
-
-On Windows, mongoose iconifies itself to the system tray icon when started.
-Right-click on the icon pops up a menu, where it is possible to stop
-mongoose, or configure it, or install it as Windows service.
-
-On UNIX and Mac, mongoose is a command line utility. Running `mongoose` in
-terminal, optionally followed by configuration parameters
-(`mongoose [OPTIONS]`) or configuration file name
-(`mongoose [config_file_name]`) starts the
-web server. Mongoose does not detach from terminal. Pressing `Ctrl-C` keys
-would stop the server.
-
-When started, mongoose first searches for the configuration file.
-If configuration file is specified explicitly in the command line, i.e.
-`mongoose path_to_config_file`, then specified configuration file is used.
-Otherwise, mongoose would search for file `mongoose.conf` in the same directory
-where binary is located, and use it.
-Configuration file is a sequence of lines, each line containing
-command line argument name and it's value. Empty lines, and lines beginning
-with `#`, are ignored. Here is the example of `mongoose.conf` file:
-
-    # mongoose.conf file
-    document_root c:\www
-    listening_ports 8080,8043s
-    ssl_certificate c:\mongoose\ssl_cert.pem
-
-When configuration file is processed, mongoose process command line arguments,
-if they are specified. Command line arguments therefore can override
-configuration file settings. Command line arguments must start with `-`.
-For example, if `mongoose.conf` has line
-`document_root /var/www`, and mongoose has been started as
-`mongoose -document_root /etc`, then `/etc` directory will be served as
-document root, because command line options take priority over
-configuration file.
-
-Mongoose can also be used to modify `.htpasswd` passwords file:
-
-    mongoose -A <htpasswd_file> <realm> <user> <passwd>
-
-Usage Examples
---------------
-
-- How to share a Windows folder: copy mongoose executable to a folder and
-  double-click the executable. The folder should be accessible via
-  [http://localhost:8080](http://localhost:8080) in any browser.
-
-- How to start mongoose at UNIX startup time in daemon mode, serving
-  directory `/var/www`: put this line in the system startup script:
-  `/path/to/mongoose -listening_ports 80 -document_root /var/www &`
-
-- How to serve user home directories using URL rewrite:
-  `mongoose -url_rewrite_patterns /~joe/=/home/joe/,/~bill=/home/bill/`
-
-Command Line Options
---------------------
-```
-
-     -A htpasswd_file domain_name user_name password
-         Add/edit user's password in the passwords file. Deleting users
-         can be done with any text editor. Functionality is similar to
-         Apache's htdigest utility.
-
-     -C cgi_pattern
-         All files that fully match cgi_pattern are treated as CGI.
-         Default pattern allows CGI files be anywhere. To restrict CGIs to
-         certain directory, use e.g. "-C /cgi-bin/**.cgi".  Default:
-         "**.cgi$|**.pl$|**.php$"
-
-     -E cgi_environment
-         Extra environment variables to be passed to the CGI script in
-         addition to standard ones. The list must be comma-separated list
-         of X=Y pairs, like this: "VARIABLE1=VALUE1,VARIABLE2=VALUE2".
-         Default: ""
-
-     -G put_delete_passwords_file
-         PUT and DELETE passwords file. This must be specified if PUT or
-         DELETE methods are used. Default: ""
-
-     -I cgi_interpreter
-         Use cgi_interpreter as a CGI interpreter for all CGI scripts
-         regardless script extension.  Mongoose decides which interpreter
-         to use by looking at the first line of a CGI script.  Default:
-         "".
-
-     -P protect_uri
-         Comma separated list of URI=PATH pairs, specifying that given
-         URIs must be protected with respected password files. Default: ""
-
-     -R authentication_domain
-         Authorization realm. Default: "mydomain.com"
-
-     -S ssi_pattern
-         All files that fully match ssi_pattern are treated as SSI.
-         Unknown SSI directives are silently ignored. Currently, two SSI
-         directives are supported, "include" and "exec".  Default:
-         "**.shtml$|**.shtm$"
-
-     -T throttle
-         Limit download speed for clients.  throttle is a comma-separated
-         list of key=value pairs, where key could be a '*' character
-         (limit for all connections), a subnet in form x.x.x.x/mask (limit
-         for a given subnet, for example 10.0.0.0/8), or an URI prefix
-         pattern (limit for the set of URIs, for example /foo/**). The
-         value is a floating-point number of bytes per second, optionally
-         followed by a `k' or `m' character, meaning kilobytes and
-         megabytes respectively. A limit of 0 means unlimited rate. The
-         last matching rule wins. For example, "*=1k,10.0.0.0/8" means
-         limit everybody to 1 kilobyte per second, but give people from
-         10/8 subnet unlimited speed. Default: ""
-
-     -a access_log_file
-         Access log file. Default: "", no logging is done.
-
-     -d enable_directory_listing
-         Enable/disable directory listing. Default: "yes"
-
-     -e error_log_file
-         Error log file. Default: "", no errors are logged.
-
-     -g global_passwords_file
-         Location of a global passwords file. If set, per-directory
-         .htpasswd files are ignored, and all requests must be authorised
-         against that file.  Default: ""
-
-     -i index_files
-         Comma-separated list of files to be treated as directory index
-         files.  Default: "index.html,index.htm,index.cgi"
-
-     -l access_control_list
-         Specify access control list (ACL). ACL is a comma separated list
-         of IP subnets, each subnet is prepended by '-' or '+' sign. Plus
-         means allow, minus means deny. If subnet mask is omitted, like
-         "-1.2.3.4", then it means single IP address. Mask may vary from 0
-         to 32 inclusive. On each request, full list is traversed, and
-         last match wins. Default setting is to allow all. For example, to
-         allow only 192.168/16 subnet to connect, run "mongoose
-         -0.0.0.0/0,+192.168/16".  Default: ""
-
-     -m extra_mime_types
-         Extra mime types to recognize, in form "extension1=type1,exten-
-         sion2=type2,...". Extension must include dot.  Example: "mongoose
-         -m .cpp=plain/text,.java=plain/text". Default: ""
-
-     -p listening_ports
-         Comma-separated list of ports to listen on. If the port is SSL, a
-         letter 's' must be appeneded, for example, "-p 80,443s" will open
-         port 80 and port 443, and connections on port 443 will be SSL-ed.
-         It is possible to specify an IP address to bind to. In this case,
-         an IP address and a colon must be prepended to the port number.
-         For example, to bind to a loopback interface on port 80 and to
-         all interfaces on HTTPS port 443, use "mongoose -p
-         127.0.0.1:80,443s". Default: "8080"
-
-     -r document_root
-         Location of the WWW root directory. Default: "."
-
-     -s ssl_certificate
-         Location of SSL certificate file. Default: ""
-
-     -t num_threads
-         Number of worker threads to start. Default: "10"
-
-     -u run_as_user
-         Switch to given user's credentials after startup. Default: ""
-
-     -w url_rewrite_patterns
-         Comma-separated list of URL rewrites in the form of "pattern=sub-
-         stitution,..." If the "pattern" matches some prefix of the
-         requested URL, then matched prefix gets substituted with "substi-
-         tution".  For example, "-w /con-
-         fig=/etc,**.doc|**.rtf=/path/to/cgi-bin/handle_doc.cgi" will
-         serve all URLs that start with "/config" from the "/etc" direc-
-         tory, and call handle_doc.cgi script for .doc and .rtf file
-         requests. If some pattern matches, no further matching/substitu-
-         tion is performed (first matching pattern wins). Use full paths
-         in substitutions. Default: ""
-
-     -x hide_files_patterns
-         A prefix pattern for the files to hide. Files that match the pat-
-         tern will not show up in directory listing and return 404 Not
-         Found if requested. Default: ""

+
+    struct mg_server *mg_create_server(void *server_param);
+
+Creates web server instance. Returns opaque instance pointer, or NULL if
+there is not enough memory. `server_param`: Could be any pointer, or NULL.
+This pointer will be passed
+to the callback functions as `struct mg_connection::server_param` field.
+A common use case is to pass `this` pointer of the C++ wrapper class
+as `user_param`, to let the callback get the pointer to the C++
+object.
+
+Note that this function doesn't make the
+server instance to serve. Serving is done by `mg_poll_server()` function.
+Mongoose has single-threaded, event-driven, asynchronous, non-blocking core.
+When server instance is created, it contains an information about
+the configuration and the state of each connection.
+Server instance is capable on listening on only one port. After creation,
+`struct mg_server` has a list
+of active connections, initially empty. It has a list of URI handlers,
+initially empty, and configuration parameters. Configuration can be
+altered by `mg_set_option()`, and new URI handlers could be added by
+`mg_add_uri_handler()`.
+
+Side-effect: on UNIX, `mg_create_server()` ignores SIGPIPE signals. If custom
+processing is required SIGPIPE, signal handler must be set up after
+calling `mg_create_server()`.
+
+Important: Mongoose does not install `SIGCHLD` handler. If CGI is used,
+`SIGCHLD` handler must be set up to reap CGI zombie processes.
+
+
+    void mg_destroy_server(struct mg_server **server);
+
+Deallocates web server instance, closes all pending connections, and makes
+server pointer a NULL pointer.
+
+    const char mg_set_option(struct mg_server *server, const char *name,
+                             const char *value);
+
+Sets a particular server option. Please refer to a separate documentation page
+that lists all available option names. Note that at least one option,
+`listening_port`, must be specified. To serve static files, `document_root`
+must be specified too. If `document_root` option is left unset, Mongoose
+will not access filesystem at all. This function returns NULL if option was
+set successfully, otherwise it returns human-readable error string. It is
+allowed to call `mg_set_option()` by the same thread that does
+`mg_poll_server()` (an IO thread) and change server configuration while it
+is serving, in between `mg_poll_server()` calls.
+
+    void mg_poll_server(struct mg_server *server, int milliseconds);
+
+This function performs one iteration of IO loop by iterating over all
+active connections, performing `select()` syscall on all sockets with a timeout
+of `milliseconds` number of milliseconds. When `select()` returns, Mongoose
+does an IO for each socket that has data to be sent or received. Application
+code must call `mg_poll_server()` in a loop. It is an error to have more then
+one thread calling `mg_poll_server()`, `mg_set_option()` or any other function
+that take `struct mg_server *` parameter. Mongoose does not
+mutex-protect `struct mg_server *`, therefore the best practice is
+to call server management functions from the same thread (an IO thread).
+
+    void mg_add_uri_handler(struct mg_server *, const char *uri, mg_handler_t);
+
+Adds an URI handler. If Mongoose gets a request and request's URI starts
+with `uri`, then specified handler is called to serve the request. Thus, an
+`uri` is a match prefix. For example, if `uri` is "/", then all requests will
+be routed to the handler, because all URIs start with `/` character.
+
+When mongoose buffers in HTTP request and successfully parses it, it calls
+appropriate URI handler immediately for GET requests. For POST requests,
+Mongoose delays the call until the whole POST request is buffered in memory.
+POST data is available to the callback as `struct mg_connection::content`,
+and POST data length is in `struct mg_connection::content_len`.
+
+Note that websocket connections are treated the same way. Mongoose buffers
+websocket frame in memory, and calls URI handler when frame is fully
+buffered. Frame data is available `struct mg_connection::content`, and
+data length is in `struct mg_connection::content_len`, i.e. very similar to
+the POST request. `struct mg_connection::is_websocket` flag indicates
+whether the request is websocket or not. Also, for websocket requests,
+there is `struct mg_connection::wsbits` field which contains first byte
+of the websocket frame which URI handler can examine. Note that to
+reply to the websocket client, `mg_websocket_write()` should be used.
+To reply to the plain HTTP client, `mg_write()` should be used.
+
+    void mg_set_http_error_handler(struct mg_server *, mg_handler_t);
+
+Adds HTTP error handler. An actual HTTP error is passed as
+`struct mg_connection::status_code` parameter. If handler returns 0, it
+means a handler has not processed the connection, and mongoose proceeds
+with sending HTTP error to the client. Otherwise, mongoose does nothing.
+
+    const char **mg_get_valid_option_names(void);
+
+Returns a NULL-terminated array of option names and their default values.
+There are two entries per option in an array: an option name followed by a
+default value. A default value could be NULL. A NULL name indicates an end
+of the array.
+
+    const char *mg_get_option(const struct mg_server *server, const char *name);
+
+Returns the value of particular configuration parameter. If
+given parameter name is not valid, NULL is returned. For valid names, return
+value is guaranteed to be non-NULL. If parameter is not set, zero-length string
+is returned.
+
+
+    int mg_iterate_over_connections(struct mg_server *,
+                                void (*func)(struct mg_connection *, void *),
+                                void *param);
+
+This is an interface primarily designed to push arbitrary data to websocket
+connections at any time. This function could be called from any thread. When
+it returns, an IO thread called `func()` on each active connection,
+passing `param` as an extra parameter. It is allowed to call `mg_send_data()` or
+`mg_websocket_write()` within a callback, cause `func` is executed in the
+context of the IO thread.
+
+    void mg_send_status(struct mg_connection *, int status_code);
+    void mg_send_header(struct mg_connection *, const char *name,
+                        const char *value);
+    void mg_send_data(struct mg_connection *, const void *data, int data_len);
+    void mg_printf_data(struct mg_connection *, const char *format, ...);
+
+These functions are used to construct a response to the client. HTTP response
+consists of three parts: a status line, zero or more HTTP headers,
+a response body.  Mongoose provides functions for all three parts:
+   * `mg_send_status()` is used to create status line. This function can be
+      called zero or once. If `mg_send_status()` is not called, then Mongoose
+      will send status 200 (success) implicitly.
+   * `mg_send_header()` adds HTTP header to the response. This function could
+      be called zero or more times.
+   * `mg_send_data()` and `mg_printf_data()` are used to send data to the
+     client. Note that Mongoose adds `Transfer-Encoding: chunked` header
+     implicitly, and sends data in chunks. Therefore, it is not necessary to
+     set `Content-Length` header.
+
+<!-- -->
+
+    int mg_websocket_write(struct mg_connection* conn, int opcode,
+                           const char *data, size_t data_len);
+
+Similar to `mg_write()`, but wraps the data into a websocket frame with a
+given websocket `opcode`. This function is available when mongoose is
+compiled with `-DUSE_WEBSOCKET`.  
+
+    const char *mg_get_header(const struct mg_connection *, const char *name);
+
+Get the value of particular HTTP header. This is a helper function.
+It traverses http_headers array, and if the header is present in the array,
+returns its value. If it is not present, NULL is returned.
+
+
+    int mg_get_var(const struct mg_connection *conn, const char *var_name,
+                   char *buf, size_t buf_len);
+
+Gets HTTP form variable. Both POST buffer and query string are inspected.
+Form variable is url-decoded and written to the buffer. On success, this
+function returns the length of decoded variable. On error, -1 is returned if
+variable not found, and -2 is returned if destination buffer is too small
+to hold the variable. Destination buffer is guaranteed to be
+'\0' - terminated if it is not NULL or zero length.
+
+    int mg_parse_header(const char *hdr, const char *var_name, char *buf,
+                        size_t buf_size);
+
+This function parses HTTP header and fetches given variable's value in a buffer.
+A header should be like `x=123, y=345, z="other value"`. This function is
+designed to parse Cookie headers, Authorization headers, and similar. Returns
+the length of the fetched value, or 0 if variable not found.
+
+    int mg_modify_passwords_file(const char *passwords_file_name,
+                                 const char *domain,
+                                 const char *user,
+                                 const char *password);
+
+Add, edit or delete the entry in the passwords file.  
+This function allows an application to manipulate .htpasswd files on the
+fly by adding, deleting and changing user records. This is one of the
+several ways of implementing authentication on the server side. For another,
+cookie-based way please refer to the examples/chat.c in the source tree.  
+If password is not NULL, entry is added (or modified if already exists).
+If password is NULL, entry is deleted.  
+Return: 1 on success, 0 on error.

+This is a small guide to help you run mongoose on Android. Currently it is
+tested on the HTC Wildfire. If you have managed to run it on other devices
+as well, please comment or drop an email in the mailing list.
+Note : You dont need root access to run mongoose on Android.
+
+- Clone Mongoose Git repo
+- Download the Android NDK from [http://developer.android.com/tools/sdk/ndk/index.html](http://developer.android.com/tools/sdk/ndk/index.html)
+- Run `/path-to-ndk/ndk-build -C /path-to-mongoose/build`

+# Mongoose Embedding Guide
+
+Embedding Mongoose is done in two steps:
+
+   1. Copy
+    [mongoose.c](https://raw.github.com/cesanta/mongoose/master/mongoose.c) and
+    [mongoose.h](https://raw.github.com/cesanta/mongoose/master/mongoose.h)
+    to your application's source tree and include them in the build.
+   2. Somewhere in the application code, call `mg_create_server()` to create
+    a server, configure it with `mg_set_option()` and loop with
+    `mg_poll_server()` until done. Call `mg_destroy_server()` to cleanup.
+
+Here's a minimal application `app.c` that embeds mongoose:
+
+    #include "mongoose.h"
+    int main(void) {
+      struct mg_server *server = mg_create_server(NULL);
+      mg_set_option(server, "document_root", ".");
+      mg_set_option(server, "listening_port", "8080");
+      for (;;) mg_poll_server(server, 1000);  // Infinite loop, Ctrl-C to stop
+      mg_destroy_server(&server);
+      return 0;
+    }
+
+To compile it, put `mongoose.c`, `mongoose.h` and `minimal.c` into one
+folder, start terminal on UNIX or Visual Studio command line prompt on Windows,
+and run the following command:
+
+    cc app.c mongoose.c -o app    # on Unix
+    cl app.c mongoose.c /TC /MD   # on Windows
+
+When run, this simple application opens port 8080 and serves static files,
+CGI files and lists directory content in the current working directory.
+
+Mongoose can call user-defined functions when certain URIs are requested.
+These functions are _called uri handlers_.  `mg_add_uri_handler()` registers
+an URI handler, and there is no restriction exist on the number of URI handlers.
+Also, mongoose can call a user-defined function when it is about to send
+HTTP error back to client. That function is called _http error handler_ and
+can be registered by `mg_set_http_error_handler()`. Handlers are called
+by Mongoose with `struct mg_connection *` pointer as a parameter, which
+has all information about the request: HTTP headers, POST or websocket
+data buffer, etcetera.
+
+Let's extend our minimal application example and
+create an URI that will be served by user's C code. The app will handle
+`/hello` URI by showing a hello message. So, when app is run,
+http://127.0.0.1:8080/hello will say hello, and here's the code:
+
+    #include <string.h>
+    #include "mongoose.h"
+
+    static int handle_hello(struct mg_connection *conn) {
+      static const char *reply = "Hello world!\n";
+      mg_write_data(conn, reply, strlen(reply));
+      return 1;
+    }
+
+    int main(void) {
+      struct mg_server *server = mg_create_server(NULL);
+      mg_set_option(server, "document_root", ".");
+      mg_set_option(server, "listening_port", "8080");
+      mg_add_uri_handler(server, "/hello", &handle_hello);
+      for (;;) mg_poll_server(server, 1000);  // Infinite loop, Ctrl-C to stop
+      mg_destroy_server(&server);
+      return 0;
+    }
+
+Below is the list of compilation flags that enable or disable certain
+features. By default, some features are enabled, and could be disabled
+by setting appropriate `NO_*` flag. Features that are disabled by default
+could be enabled by setting appropriate `USE_*` flag. Bare bones Mongoose
+is quite small, about 30 kilobytes of compiled x86 code. Each feature adds
+a couple of kilobytes to the executable size, and also has some runtime penalty.
+
+    -DNO_AUTH         Disable MD5 authorization support
+    -DNO_CGI          Disable CGI support
+    -DNO_DAV          Disable WebDAV support (PUT, DELETE, MKCOL, PROPFIND)
+    -DNO_DIRECTORY_LISTING  Disable directory listing
+    -DNO_LOGGING      Disable access/error logging
+    -DNO_WEBSOCKET    Disable WebSocket support
+
+    -DUSE_IPV6          Enable IPv6 support
+    -DUSE_LUA           Enable Lua scripting
+    -DUSE_LUA_SQLITE3   Enable sqlite3 binding for Lua

+# Mongoose FAQ
+
+### PHP doesn't work: getting empty page, or 'File not found' error
+
+The reason for that is wrong paths to the interpreter. Remember that with PHP,
+correct interpreter is `php-cgi.exe` (`php-cgi` on UNIX). Solution: specify
+full path to the PHP interpreter, e.g.:
+
+    mongoose -cgi_interpreter /full/path/to/php-cgi
+
+### Mongoose fails to start
+
+If Mongoose exits immediately when run, this
+usually indicates a syntax error in the configuration file
+(named `mongoose.conf` by default) or the command-line arguments.
+Syntax checking is omitted from Mongoose to keep its size low. However,
+the Manual should be of help. Note: the syntax changes from time to time,
+so updating the config file might be necessary after executable update.
+
+### Embedding with OpenSSL on Windows might fail because of calling convention
+
+To force Mongoose to use `__stdcall` convention, add `/Gz` compilation
+flag to the Visual Studio project settings.

+# Mongoose Internals
+
+Mongoose has single-threaded, event-driven, asynchronous, non-blocking core.
+`mg_create_server()` creates a web server instance. An instance is a container
+for the config options and list of active connections. To do the actual
+serving, user must call `mg_poll_server()`, which iterates over all
+active connections, performing `select()` syscall on all sockets with a
+timeout of specified number of milliseconds. When `select()` returns, Mongoose
+does an IO for each socket that has data to be sent or received. Application
+code must call `mg_poll_server()` in a loop.
+
+Mongoose server instance is designed to be used by a single thread.
+It is an error to have more then
+one thread calling `mg_poll_server()`, `mg_set_option()` or any other function
+that take `struct mg_server *` parameter. Mongoose does not
+mutex-protect `struct mg_server *`, therefore the best practice is
+to call server management functions from the same thread (an IO thread).
+On a multi-core systems, many server instances can be created, sharing the
+same listening socket and managed by separate threads (see [multi_threaded.c](https://github.com/cesanta/mongoose/blob/master/examples/multi_threaded.c))
+example.
+
+It is an error to pass and store `struct mg_connection *` pointers for
+later use to send data. The reason is that they can be invalidated by the
+next `mg_poll_server()` call. For such a task,
+there is `mg_iterate_over_connections()` API
+exists, which sends a callback function to the IO thread, then IO thread
+calls specified function for all active connection.
+
+When mongoose buffers in HTTP request and successfully parses it, it calls
+appropriate URI handler immediately for GET requests. For POST requests,
+Mongoose delays the call until the whole POST request is buffered in memory.
+POST data is available to the callback as `struct mg_connection::content`,
+and POST data length is in `struct mg_connection::content_len`.
+
+Note that websocket connections are treated the same way. Mongoose buffers
+websocket frame in memory, and calls URI handler when frame is fully
+buffered. Frame data is available `struct mg_connection::content`, and
+data length is in `struct mg_connection::content_len`, i.e. very similar to
+the POST request. `struct mg_connection::is_websocket` flag indicates
+whether the request is websocket or not. Also, for websocket requests,
+there is `struct mg_connection::wsbits` field which contains first byte
+of the websocket frame which URI handler can examine. Note that to
+reply to the websocket client, `mg_websocket_write()` should be used.
+To reply to the plain HTTP client, `mg_write()` should be used.

+# Mongoose Lua Server Pages
+
+Pre-built Windows and Mac mongoose binaries support Lua Server Pages
+functionality.
+That means it is possible to write PHP-like scripts with mongoose
+using Lua programming language instead of PHP. Lua is known
+for it's speed and small size. Mongoose uses Lua version 5.2.1, the
+documentation for it can be found at
+[Lua 5.2 reference manual](http://www.lua.org/manual/5.2/).
+
+To create a Lua Page, make a file that is called `<something>.lp`. For example,
+let's say it is going to be `my_page.lp`. It is important to have a file
+name that ends up with `.lp`, cause this is the way mongoose recognises
+Lua Page file. The contents of the file, just like
+with PHP, is HTML with embedded Lua code. Lua code must be enclosed within
+`<?  ?>` blocks, and can appear anywhere on the page.
+
+Mongoose does not send HTTP headers for Lua pages. Therefore,
+every Lua Page must begin with HTTP status line and headers, like this:
+
+    <? mg.write('HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n') ?>
+    <html><body>
+      <span>Today is:</span> <? mg.write(os.date("%A")) ?>
+    </body></html>
+
+Note that this example uses function `mg.write()`, which prints data to the
+web page. Using function `mg.write()` is the way to generate web content from
+inside Lua code. In addition to `mg.write()`, all standard library functions
+are accessible from the Lua code (please check reference manual for details).
+Information about the request is available in `mg.request_info` object.
+I contains request method, all headers, etcetera. Please refer to
+`struct mg_request_info` definition in
+[mongoose.h](https://github.com/cesanta/mongoose/blob/master/mongoose.h)
+to see what is available in `mg.request_info`. Also,
+[page.lp](https://github.com/cesanta/mongoose/blob/master/test/page.lp) and
+[prime_numbers.lp](https://github.com/cesanta/mongoose/blob/master/examples/lua/prime_numbers.lp)
+contain some example code that uses `request_info` and other functions,
+like form submission.
+
+Mongoose exports the following to the Lua server page:
+
+    mg.write(str)     -- writes string to the client
+    mg.onerror(msg)   -- error handler, can be overridden
+    mg.request_info   -- a table with request information
+    sqlite3           -- Sqlite3 interface
+
+slite3 functions are documented at [lua.sqlite.org](http://lua.sqlite.org/),
+and usage example is at
+[page.lp](https://github.com/cesanta/mongoose/blob/master/test/page.lp).
+
+Using Lua scripting it is easy to emulate SSI functionality. For example,
+to include the content of another file, one can write:
+
+    <? mg.write(io.open('MY_FILE.TXT'):read('*all')) ?>
+
+To serve a Lua Page, mongoose creates Lua context. That context is used for
+all Lua blocks within the page. That means, all Lua blocks on the same page
+share the same context. If one block defines a variable, for example, that
+variable is visible in the block that follows.

+# Mongoose Configuration Options
+
+### access\_control\_list
+An Access Control List (ACL) allows restrictions to be put on the list of IP
+addresses which have access to the web server. In the case of the Mongoose
+web server, the ACL is a comma separated list of IP subnets, where each
+subnet is prepended by either a `-` or a `+` sign. A plus sign means allow,
+where a minus sign means deny. If a subnet mask is omitted, such as `-1.2.3.4`,
+this means to deny only that single IP address.
+
+Subnet masks may vary from 0 to 32, inclusive. The default setting is to allow
+all accesses. On each request the full list is traversed, and
+the last match wins. Example: `$ mongoose -access_control_list -0.0.0.0/0,+192.168/16` to deny all acccesses except from 192.168/16 subnet. To learn
+more about subnet masks, see the
+[Wikipedia page on Subnetwork](http://en.wikipedia.org/wiki/Subnetwork)
+
+Default: not set, all accesses are allowed.
+
+### access\_log\_file
+Path to a file for access logs. Either full path, or relative to the
+mongoose executable. Default: not set, no query logging is done.
+
+### auth_domain
+Authorization realm used in `.htpasswd` authorization. Default: `mydomain.com`
+
+### cgi_interpreter
+Path to an executable to use as CGI interpreter for __all__ CGI scripts
+regardless script extension.
+for an interpreter. Default: not set, Mongoose looks at
+[shebang line](http://en.wikipedia.org/wiki/Shebang_(Unix\).
+
+For example, if both PHP and perl CGIs are used, then
+`#!/path/to/php-cgi.exe` and `#!/path/to/perl.exe` must be first lines of the
+respective CGI scripts. Note that paths should be either full file paths,
+or file paths relative to the directory where mongoose server is located.
+
+If all CGIs use the same interpreter, for example they are all PHP, then
+`cgi_interpreter` option can be set to the path to `php-cgi.exe` executable and
+shebang line in the CGI scripts can be omitted.
+Note that PHP scripts must use `php-cgi.exe` executable, not `php.exe`.
+
+### cgi_pattern
+All files that match `cgi_pattern` are treated as CGI files. Default pattern
+allows CGI files be anywhere. To restrict CGIs to a certain directory,
+use `/path/to/cgi-bin/**.cgi` as pattern. Note that full file path is
+matched against the pattern, not the URI. Note: if `MONGOOSE_CGI` environment
+variable is set, then Mongoose passes it to the CGI script.
+
+Default: `**.cgi$|**.pl$|**.php$`
+
+### dav\_auth\_file
+Authentication file for WebDAV mutation requests: `PUT`, `DELETE`, `MKCOL`.
+The format of that file is the same as for the `.htpasswd` file
+used for digest authentication. It can be created and managed by
+`mongoose -A` command. Default: not set, WebDAV mutations are disallowed.
+
+### document_root
+A directory to serve. Default: current working directory.
+
+### enable\_directory\_listing
+Enable directory listing, either `yes` or `no`. Default: `yes`.
+
+### error\_log\_file
+Path to a file for error logs. Either full path, or relative to the
+mongoose executable. Default: not set, no errors are logged.
+
+### extra\_mime\_types
+Extra mime types to recognize, in form `extension1=type1,extension2=type2,...`.
+Extension must include dot.  Example:
+`mongoose -extra_mime_types .cpp=plain/text,.java=plain/text`. Default: not set.
+
+
+### global\_auth\_file
+Path to a global passwords file, either full path or relative to the mongoose
+executable. If set, per-directory `.htpasswd` files are ignored,
+and all requests are authorised against that file. Use `mongoose -A` to
+manage passwords, or third party utilities like
+[htpasswd-generator](http://www.askapache.com/online-tools/htpasswd-generator).
+Default: not set, per-directory `.htpasswd` files are respected.
+
+### hide\_files\_patterns
+A pattern for the files to hide. Files that match the pattern will not
+show up in directory listing and return `404 Not Found` if requested. Pattern
+must be for a file name only, not including directory name, e.g.
+`mongoose -hide_files_patterns secret.txt|even_more_secret.txt`. Default:
+not set.
+
+### idle\_timeout\_ms
+Timeout for idle connections. Default: 30000 (30 seconds)
+
+### index_files
+Comma-separated list of files to be treated as directory index
+files. Default: `index.html,index.htm,index.cgi,index.shtml,index.php`
+
+### ssl_certificate
+Path to SSL certificate file. The file must be in PEM format,
+and it must have both private key and certificate, see for example
+[ssl_cert.pem](https://github.com/cesanta/mongoose/blob/master/build/ssl_cert.pem). If this option is set, then Mongoose serves SSL connections on
+`listening_port`. Default: not set.
+
+### listening_port
+Port to listen on. Port could be prepended by the specific IP address to bind
+to, e.g. `mongoose -listening_port 127.0.0.1:8080`. Otherwise Mongoose
+will bind to all addresses.  Default: 8080.
+
+### run\_as\_user
+Switch to given user credentials after startup. UNIX-only. This option is
+required when mongoose needs to bind on privileged port on UNIX, e.g.
+
+    $ sudo mongoose -listening_ports 80 -run_as_user nobody
+
+Default: not set.
+
+### url\_rewrites
+Comma-separated list of URL rewrites in the form of
+`uri_pattern=file_or_directory_path`. When Mongoose receives the request,
+it constructs the file name to show by combining `document_root` and the URI.
+However, if the rewrite option is used and `uri_pattern` matches the
+requested URI, then `document_root` is ignored. Insted,
+`file_or_directory_path` is used, which should be a full path name or
+a path relative to the web server's current working directory. Note that
+`uri_pattern`, as all mongoose patterns, is a prefix pattern. If `uri_patters`
+is a number, then it is treated as HTTP error code, and `file_or_directory_path`
+should be an URI to redirect to. Mongoose will issue `302` temporary redirect
+to the specified URI, appending two parameters:
+`?code=<http_error_code&orig_uri=<original_uri>`.
+
+This makes it possible to serve many directories outside from `document_root`,
+redirect all requests to scripts, and do other tricky things. Examples:
+
+    # Redirect all accesses to `.doc` files to a special script
+    mongoose -url_rewrites **.doc$=/path/to/cgi-bin/handle_doc.cgi
+
+    # Implement user home directories support
+    mongoose -url_rewrites /~joe/=/home/joe/,/~bill=/home/bill/
+
+    # Redirect 404 errors to a specific error page
+    mongoose -url_rewrites 404=/cgi-bin/error.cgi
+
+Default: not set.

+# Mongoose SSL guide
+
+SSL is a protocol that makes web communication secure. To enable SSL
+in mongoose, 3 steps are required:
+
+   1. Valid certificate file must be created
+   2. `ssl_certificate` options must be set to contain path to the
+       certificate file.
+   3. `listening_ports` option must contain a port number with letter `s`
+        appended to it, which instructs Mongoose to use SSL for all connections
+        made to that port.
+
+Below is the `mongoose.conf` file snippet for typical SSL setup:
+
+    document_root     www_root        # Serve files in www_root directory
+    listening_ports   80r,443s        # Redirect all HTTP requests to HTTPS
+    ssl_certificate   ssl_cert.pem    # Location of certificate file
+
+## How to create SSL certificate file
+
+SSL certificate file is a text file that must contain at least two
+sections:
+
+   1. A private key
+   2. A certificate
+
+Both sections should be chunks of text in PEM format. When PEM file is
+opened in a text editor, it looks like this:
+
+    -----BEGIN RSA PRIVATE KEY-----
+    MIIEogIBAAKCAQEAwONaLOP7EdegqjRuQKSDXzvHmFMZfBufjhELhNjo5KsL4ieH
+    hYN0Zii2yTb63jGxKY6gH1R/r9dL8kXaJmcZrfSa3AgywnteJWg=
+    -----END RSA PRIVATE KEY-----
+    -----BEGIN CERTIFICATE-----
+    MIIDBjCCAe4CCQCX05m0b053QzANBgkqhkiG9w0BAQQFADBFMQswCQYDVQQGEwJB
+    SEGI4JSxV56lYg==
+    -----END CERTIFICATE-----
+
+Two aforementioned sections are clearly seen. Typically, those section
+are bigger then in the example shown. The text between the `BEGIN` and
+`END` is the text representation of binary data, a private key and a
+certificate. Therefore, in order to create a certificate file,
+
+   * private key must be converted to PEM format
+   * certificate must be converted to PEM format
+   * those two should be concatenated into a single file
+
+If the certificate chain in used, a chain file also needs to be
+converted into PEM format and appended to the certificate file.
+
+## How SSL works
+
+SSL is a protocol that can encrypt communication between two parties. If third
+party observes all messages passed by, it would be very
+hard for the third party (though not impossible) to decrypt the communication.
+
+The idea is based on so-called public key encryption. Communicating parties
+have two keys: a public key and a private key. A public key is advertised
+to everybody, and it is contained in a certificate. A private key is kept
+secret. Security algorithm works in a way that anybody can encrypt
+a message using public key, and only private key can decrypt it.
+
+This is why web server needs both private key and certificate: private key
+is used to decrypt incoming messages, and certificate is used to tell the
+public key to the other party. When communication starts, parties exchange
+their public keys, and keep private keys to themselves. Man-in-the-middle
+who observes the communication is unable to decrypt the messages cause
+private keys are required for decryption.
+
+Encryption algorithms are built on top of hard mathematical problem, which
+makes it very expensive for man-in-the-middle to compute private keys.
+For example, RSA algorithm is based on a mathematical problem of factorization.
+It is easy to generate two very large prime numbers `P` and `Q` and make
+a product `P * Q`. But given a product, it is very hard to recover these
+two prime numbers - this is called factorization.

+# Mongoose User Guide
+
+Mongoose is small and easy to use web server built on top of
+mongoose library. It is designed with maximum simplicity in mind. For example,
+to share any directory, just drop mongoose executable file in that directory,
+double-click it (on UNIX, run it from shell) and launch a browser at
+[http://localhost:8080](http://localhost:8080) Note that 'localhost' should
+be changed to a machine's name if a folder is accessed from other computer.
+
+On Windows and Mac, Mongoose iconifies itself to the system tray when started.
+Right-click on the icon pops up a menu, where it is possible to stop
+mongoose, or configure it.
+
+On UNIX, `mongoose` is a command line utility. Running `mongoose` in
+terminal, optionally followed by configuration parameters
+(`mongoose [OPTIONS]`) or configuration file name
+(`mongoose [config_file_name]`) starts the
+web server:
+
+    $ mongoose -document_root /var/www  # Running mongoose with cmdline options
+    $ mongoose /etc/my_config.txt       # Running mongoose with config file
+    $ mongoose                          # Running with no parameters. This will
+                                        # serve current directory on port 8080
+
+Mongoose does not detach from terminal. Pressing `Ctrl-C` keys
+stops the server.
+
+When started, mongoose first searches for the configuration file.
+If configuration file is specified explicitly in the command line, then
+specified configuration file is used.
+Otherwise, mongoose would search for file `mongoose.conf` in the same directory
+where binary is located, and use it. Configuration file can be absent.
+
+Configuration file is a sequence of lines, each line containing
+command line argument name and it's value. Empty lines and lines beginning
+with `#` are ignored. Here is the example of `mongoose.conf` file:
+
+    # This is a comment
+    document_root C:\www
+    listening_port 80
+    ssl_certificate C:\mongoose\ssl_cert.pem
+
+Command line arguments are highest priority and can override
+configuration file settings. For example, if `mongoose.conf` has line
+`document_root /var/www`, and mongoose has been started as
+`mongoose -document_root /etc`, then `/etc` directory will be used as
+document root.
+
+Note that configuration options on the command line must start with `-`,
+and their names are the same as in the config file. Exampli gratia,
+the following two setups are equivalent:
+
+    $ mongoose -listening_port 1234 -document_root /var/www
+
+    $ cat > mongoose.conf
+    listening_ports 1234
+    document_root /var/www
+    ^D
+    $ mongoose
+
+Mongoose can also be used to modify `.htpasswd` passwords file:
+
+    $ mongoose -A .htpasswd mydomain.com user_name user_password
+
+Unlike other web servers, mongoose does not require CGI scripts be located in
+a special directory. CGI scripts can be anywhere. CGI (and SSI) files are
+recognized by the file name pattern. Mongoose uses shell-like glob
+patterns. Pattern match starts at the beginning of the string, so essentially
+patterns are prefix patterns. Syntax is as follows:
+
+     **      Matches everything
+     *       Matches everything but slash character, '/'
+     ?       Matches any character
+     $       Matches the end of the string
+     |       Matches if pattern on the left side or the right side matches.
+
+All other characters in the pattern match themselves. Examples:
+
+    **.cgi$      Any string that ends with .cgi
+    /foo         Any string that begins with /foo
+    **a$|**b$    Any string that ends with a or b
+
+To restrict CGI files only to `/cgi-bin/` directory, use this setting:
+
+    $ mongoose -cgi_pattern /cgi-bin/*.cgi # Emulate /cgi-bin/ restriction

-.Sh NAME
-.Nm mongoose
-.Nd lightweight web server
-.Sh SYNOPSIS
-.Nm
-.Op Ar config_file
-.Op Ar OPTIONS
-.Nm
-.Fl A Ar htpasswd_file domain_name user_name password
-.Sh DESCRIPTION
-.Nm
-is small, fast and easy to use web server with CGI, SSL, MD5 authorization,
-and basic SSI support.
-.Pp
-.Nm
-does not detach from terminal, and uses current working directory
-as the web root, unless
-.Fl r
-option is specified.
-It is possible to specify multiple ports to listen on. For example, to make
-mongoose listen on HTTP port 80 and HTTPS port 443, one should start it as:
-.Nm
-.Fl s Ar cert.pem Fl p Ar 80,443s
-.Pp
-Unlike other web servers,
-.Nm
-does not require CGI scripts be put in a special directory. CGI scripts can
-be anywhere. CGI (and SSI) files are recognized by the file name pattern.
-.Nm
-uses shell-like glob patterns with the following syntax:
-.Bl -tag -compact -width indent
-.It **
-Matches everything
-.It *
-Matches everything but slash character, '/'
-.It ?
-Matches any character
-.It $
-Matches the end of the string
-.It |
-Matches if pattern on the left side or the right side matches. Pattern on the
-left side is matched first
-.El
-All other characters in the pattern match themselves.
-.Pp
-If no arguments are given,
-.Nm
-searches for a configuration file called "mongoose.conf" in the same directory
-where mongoose binary is located. Alternatively, a file name could be
-specified in the command line. Format of the configuration file is the same
-as for the command line options except that each option must be specified
-on a separate line, leading dashes for option names must be omitted.
-Lines beginning with '#' and empty lines are ignored.
-.Pp
-.Sh OPTIONS
-.Bl -tag -width indent
-.It Fl A Ar htpasswd_file domain_name user_name password
-Add/edit user's password in the passwords file. Deleting users can be done
-with any text editor. Functionality is similar to Apache's
-.Ic htdigest
-utility.
-.It Fl C Ar cgi_pattern
-All files that fully match cgi_pattern are treated as CGI.
-Default pattern allows CGI files be
-anywhere. To restrict CGIs to certain directory, use e.g. "-C /cgi-bin/**.cgi".
-Default: "**.cgi$|**.pl$|**.php$"
-.It Fl E Ar cgi_environment
-Extra environment variables to be passed to the CGI script in addition to
-standard ones. The list must be comma-separated list of X=Y pairs, like this:
-"VARIABLE1=VALUE1,VARIABLE2=VALUE2". Default: ""
-.It Fl G Ar put_delete_passwords_file
-PUT and DELETE passwords file. This must be specified if PUT or
-DELETE methods are used. Default: ""
-.It Fl I Ar cgi_interpreter
-Use
-.Ar cgi_interpreter
-as a CGI interpreter for all CGI scripts regardless script extension.
-Mongoose decides which interpreter to use by looking at
-the first line of a CGI script.  Default: "".
-.It Fl P Ar protect_uri
-Comma separated list of URI=PATH pairs, specifying that given URIs
-must be protected with respected password files. Default: ""
-.It Fl R Ar authentication_domain
-Authorization realm. Default: "mydomain.com"
-.It Fl S Ar ssi_pattern
-All files that fully match ssi_pattern are treated as SSI.
-Unknown SSI directives are silently ignored. Currently, two SSI directives
-are supported, "include" and "exec".  Default: "**.shtml$|**.shtm$"
-.It Fl T Ar throttle
-Limit download speed for clients.
-.Ar throttle
-is a comma-separated list of key=value pairs, where
-key could be a '*' character (limit for all connections), a subnet in form
-x.x.x.x/mask (limit for a given subnet, for example 10.0.0.0/8), or an
-URI prefix pattern (limit for the set of URIs, for example /foo/**). The value
-is a floating-point number of bytes per second, optionally followed by a
-`k' or `m' character, meaning kilobytes and megabytes respectively. A limit
-of 0 means unlimited rate. The last matching rule wins. For example,
-"*=1k,10.0.0.0/8" means limit everybody to 1 kilobyte per second, but give
-people from 10/8 subnet unlimited speed. Default: ""
-.It Fl a Ar access_log_file
-Access log file. Default: "", no logging is done.
-.It Fl d Ar enable_directory_listing
-Enable/disable directory listing. Default: "yes"
-.It Fl e Ar error_log_file
-Error log file. Default: "", no errors are logged.
-.It Fl g Ar global_passwords_file
-Location of a global passwords file. If set, per-directory .htpasswd files are
-ignored, and all requests must be authorised against that file.  Default: ""
-.It Fl i Ar index_files
-Comma-separated list of files to be treated as directory index files.
-Default: "index.html,index.htm,index.cgi"
-.It Fl l Ar access_control_list
-Specify access control list (ACL). ACL is a comma separated list
-of IP subnets, each subnet is prepended by '-' or '+' sign. Plus means allow,
-minus means deny. If subnet mask is
-omitted, like "-1.2.3.4", then it means single IP address. Mask may vary
-from 0 to 32 inclusive. On each request, full list is traversed, and
-last match wins. Default setting is to allow all. For example, to allow only
-192.168/16 subnet to connect, run "mongoose -0.0.0.0/0,+192.168/16".
-Default: ""
-.It Fl m Ar extra_mime_types
-Extra mime types to recognize, in form
-"extension1=type1,extension2=type2,...". Extension must include dot.
-Example: "mongoose -m .cpp=plain/text,.java=plain/text". Default: ""
-.It Fl p Ar listening_ports
-Comma-separated list of ports to listen on. If the port is SSL, a letter 's'
-must be appeneded, for example, "-p 80,443s" will open port 80 and port 443,
-and connections on port 443 will be SSL-ed. It is possible to specify an
-IP address to bind to. In this case, an IP address and a colon must be
-prepended to the port number. For example, to bind to a loopback interface
-on port 80 and to all interfaces on HTTPS port 443, use
-"mongoose -p 127.0.0.1:80,443s". Default: "8080"
-.It Fl r Ar document_root
-Location of the WWW root directory. Default: "."
-.It Fl s Ar ssl_certificate
-Location of SSL certificate file. Default: ""
-.It Fl t Ar num_threads
-Number of worker threads to start. Default: "10"
-.It Fl u Ar run_as_user
-Switch to given user's credentials after startup. Default: ""
-.It Fl w Ar url_rewrite_patterns
-Comma-separated list of URL rewrites in the form of
-"pattern=substitution,..." If the "pattern" matches some prefix
-of the requested URL, then matched prefix gets substituted with "substitution".
-For example, "-w /config=/etc,**.doc|**.rtf=/path/to/cgi-bin/handle_doc.cgi"
-will serve all URLs that start with "/config" from the "/etc" directory, and
-call handle_doc.cgi script for .doc and .rtf file requests. If some pattern
-matches, no further matching/substitution is performed
-(first matching pattern wins). Use full paths in substitutions. Default: ""
-.It Fl x Ar hide_files_patterns
-A prefix pattern for the files to hide. Files that match the pattern will not
-show up in directory listing and return 404 Not Found if requested. Default: ""
-.El
-.Pp
-.Sh EMBEDDING
-.Nm
-was designed to be embeddable into C/C++ applications. Since the
-source code is contained in single C file, it is fairly easy to embed it
-and follow the updates. Please refer to http://code.google.com/p/mongoose
-for details.
-.Pp
-.Sh EXAMPLES
-.Bl -tag -width indent
-.It Nm Fl r Ar /var/www Fl s Ar /etc/cert.pem Fl p Ar 8080,8043s
-Start serving files from /var/www. Listen on port 8080 for HTTP, and 8043
-for HTTPS connections.  Use /etc/cert.pem as SSL certificate file.
-.It Nm Fl l Ar -0.0.0.0/0,+10.0.0.0/8,+1.2.3.4
-Deny connections from everywhere, allow only IP address 1.2.3.4 and
-all IP addresses from 10.0.0.0/8 subnet to connect.
-.It Nm Fl w Ar **=/usr/bin/script.cgi
-Invoke /usr/bin/script.cgi for every incoming request, regardless of the URL.
