 # Mongoose API Reference
    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, and sleeping
 for `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.

 # Mongoose Build on Android
 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`
  That should generate mongoose/lib/armeabi/mongoose
 - Using the adb tool (you need to have Android SDK installed for that),
  push the generated mongoose binary to `/data/local` folder on device.
 - From adb shell, navigate to `/data/local` and execute `./mongoose`.
 - To test if the server is running fine, visit your web-browser and
  navigate to `http://127.0.0.1:8080` You should see the `Index of /` page.

 # 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
    -DUSE_SSL           Enable SSL
    -DUSE_POST_SIZE_LIMIT=X     POST requests larger than X will be rejected
    -DUSE_EXTRA_HTTP_HEADERS=X  Append X to the HTTP headers for static files
 Mongoose source code contains a well-commented example code, listed below:
   * [hello.c](https://github.com/cesanta/mongoose/blob/master/examples/hello.c)
   is a minimalisting hello world example

 # 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.
 When mongoose server instance is created, it contains an information about
 the configuration and the state of each connection:
    struct mg_server {
      sock_t listening_sock;          // Listening socket
      union socket_address lsa;       // Listening socket address
      struct linked_list_link active_connections;
      struct linked_list_link uri_handlers;
      char *config_options[NUM_OPTIONS];
      ...
    };
 A server instance is capable on listening on only one port. After creation,
 a server instance 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()`.

 # 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\_rewrite\_patterns
 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.
 This makes it possible to serve many directories outside from `document_root`,
 redirect all requests to scripts, and do other tricky things. For example,
 to redirect all accesses to `.doc` files to a special script, do:
    mongoose -url_rewrite_patterns **.doc$=/path/to/cgi-bin/handle_doc.cgi
 Or, to imitate user home directories support, do:
    mongoose -url_rewrite_patterns /~joe/=/home/joe/,/~bill=/home/bill/

 # 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

 # Arduino Restful Client
 This example demonstrates how to use [Mongoose](https://www.cesanta.com/mongoose) to send HTTP commands from Arduino.
 Example sends free memory size and current board uptime, but it can be modified to send any user-specific data.
 At the moment this example supports [Arduino Mega 2560](http://arduino.cc/en/Main/ArduinoBoardMega2560) board (and compatible) with either W5100-based
 network shield (like [Arduino Ethernet Shield](http://arduino.cc/en/Main/ArduinoEthernetShield)) or [CC3000](http://www.ti.com/product/cc3000)-based WIFI Shield.
 ## Build and run instructions:
 ###To run with Arduino Ethernet (W5100) shield:
 1. Add (Sketch->Add file...) the following files to sketch:
     - /mongoose/mongoose.h
     - /mongoose/mongoose.c
     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
 3. Buils and start (in console) /Users/alex/Projects/mongoose/examples/restful_server example
 4. Make `board_ip` and `board_mac` variables suitable for your network and board
 5. Change IP address in `s_target_address` variable to IP address of host running restful_server
 6. Uncomment line `#include <Ethernet.h>`
 7. Compile and flash sketch
 8. restful_server will start to show current uptime and free memory size (with 5 seconds interval)
 ###To run with Adafruit WiFi (CC3000) shield:
 1. Add (Sketch->Add files...) the following files to sketch:
     - /mongoose/mongoose.h
     - /mongoose/mongoose.c
     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
 2. Import Adafruit CC3000 library for mongoose
    (select Sketch->Import Library...->Add library... and point
     /mongoose/platforms/arduino_wifi_CC3000/adafruit_CC3000_lib_mongoose folder)
 3. Buils and start (in console) /Users/alex/Projects/mongoose/examples/restful_server example
 4. Make the following variables suitable for your network
     - `board_ip`
     - `subnet_mask`
     - `gateway`
     - `dns`
     - `wlan_ssid`
     - `wlan_pwd`
     - `wlan_security`
 5. Change IP address in `s_target_address` variable to IP address of host running restful_server
 6. Uncomment line `#include <Adafruit_CC3000.h>`
 8. Compile and flash sketch
 9. restful_server will start to show current uptime and free memory size (with 5 seconds interval)

 # Arduino Restful Server
 This example demonstrates how to use [Mongoose](https://www.cesanta.com/mongoose) to control Arduino
 using HTTP requests.
 Example just blinks by LED when Mongoose receives HTTP command, but it can be modified to execute any user-specific code.
 At the moment this example supports [Arduino Mega 2560](http://arduino.cc/en/Main/ArduinoBoardMega2560) board (and compatible) with either W5100-based
 network shield (like [Arduino Ethernet Shield](http://arduino.cc/en/Main/ArduinoEthernetShield)) or [CC3000](http://www.ti.com/product/cc3000)-based WIFI Shield.
 ## Build and run instructions:
 ###To run with Arduino Ethernet (W5100) shield:
 1. Add (Sketch->Add file...) the following files to sketch:
     - /mongoose/mongoose.h
     - /mongoose/mongoose.c
     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
 2. Make `board_ip` and `board_mac` variables suitable for your network and board
 3. Uncomment line `#include <Ethernet.h>`
 4. Compile and flash sketch
 5. Run `curl http://<board_ip/blink`
   LED attached to PIN 13 will blink and board free memory size and board uptime will be displayed.
 ###To run with Adafruit WiFi (CC3000) shield:
