-Overview
+# <img src="http://www.cesanta.com/hubfs/www.cesanta.com/Images/mongoose_library.png" width="64" height="64"> Mongoose - Embedded Web Server
---------
 
-Mongoose is easy to use web server. It also can be used as embedded web server library to provide web interface to applications.  
+[![Join the chat at https://gitter.im/cesanta/mongoose](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/cesanta/mongoose?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
 
-Mongoose executable does not depend on any external library or configuration. If it is copied to any directory and launched from there, it starts to serve that directory on port 8080 (so to access files, go to http://localhost:8080). If some additional config is required - for example, different listening port or IP-based access control, that can be done via command line flags or configuration file, which should be created in the same directory where mongoose itself lives. This makes Mongoose perfect for all sorts of demos, quick tests, file sharing, and Web programming.
+![](https://img.shields.io/badge/license-GPL_2-green.svg "License")
 
 
-Features
+Mongoose is ideal for embedded environments, it has been designed as an open
---------
+source platform for connecting devices and bringing them online.
+[Mongoose](https://www.cesanta.com/products)
+has been on the market since 2004 and attracted
+over 1 million cumulative downloads.
 
-- Crossplatform - works on Windows, MacOS and most flavors of UNIX
+It provides easy to use event-driven interface that allows to implement
-- CGI, SSL, SSI, Digest (MD5) authorization, Websocket, WEbDAV support
+network protocols or scalable network applications  with little effort.
-- Lua server pages (like PHP, but using Lua as a language instead of PHP)
+Mongoose helps developers to manage the complexity of network programming
-- Resumed download, URL rewrite, IP-based ACL, Windows service
+and let them concentrate on the logic, saving time and money.
-- Excluding files from serving by URI pattern (file blacklist)
+
-- Download speed limit based on client subnet or URI pattern
+[Download Mongoose Source Code here](http://hubs.ly/H0150FK0)
-- Small footprint: executable size is 50 kB on Linux 2.6 i386 system
+
-- 130 kilobytes Windows executable with all of the above compiled in, and no dependencies
+> Nothing overdone. Nothing less. So unbelievably easy to use.
-- Embeddable with simple and clean API ([mongoose.h](https://github.com/valenok/mongoose/blob/master/mongoose.h)). The source is in single [mongoose.c](https://github.com/valenok/mongoose/blob/master/mongoose.c) file to make things easy.
+> Just how good software should be!
-- Embedding examples: [hello.c](https://github.com/valenok/mongoose/blob/master/examples/hello.c), [post.c](https://github.com/valenok/mongoose/blob/master/examples/post.c), [upload.c](https://github.com/valenok/mongoose/blob/master/examples/upload.c), [websocket.c](https://github.com/valenok/mongoose/blob/master/examples/websocket.c)

-
-  Mongoose: wraps all functions that accept struct mg_context pointer as

+# 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)

+# Mongoose-based HTTP load balancer
+
+## Configuration
+
+Load balancer is configured with command-line flags.
+
+### Global flags
+
+* `-p port` – TCP port to listen on. Default: 8000.
+* `-l log_file` – path to the log file. Default: none.
+* `-s ssl_cert` – path to SSL certificate. Default: none.
+
+### Backend configuration
+
+Main flag is `-b uri_prefix host_port` – it adds a new backend for a given
+URI prefix. Example: `-b /stuff/ 127.0.0.1:8080` will route all requests that
+start with '/stuff/' to a backend at port 8080 on localhost. There is a special
+syntax for `uri_prefix` that allows you to change the URIs that get passed to
+backends:
+
+* `-b /stuff/=/ 127.0.0.1:8080` – for '/stuff/thing' backend will see '/thing'.
+* `-b /stuff/=/other/ 127.0.0.1:8080` – '/stuff/thing' => '/other/thing'.
+
+Also there are few per-backend flags that can be placed before `-b` and apply
+only to the next backend:
+
+* `-r` – instead of proxying requests load balancer will reply with 302 
+redirect.
+* `-v vhost` – match not only URI prefix but 'Host:' header as well.
+
+### Example
+
+```
+load_balancer -s path/to/cert.pem \
+  -v example.com -b /site/=/ 127.0.0.1:8080 \
+  -b /static/ 127.0.0.1:8081 \
+  -b /static/ 127.0.0.1:8082
+``` 
+
+In this example requests to 'example.com/site/' will be forwarded to the
+backend on port 8080 with '/site' prefix stripped off and requests to
+'/static/' on any virtual host will be balanced in round-robin fashion between
+backends on ports 8081 and 8082.

+= Raspberry Pi camera/LED demo
+
+== Overview
+
+The link:/[demo] consists of web app providing access to a webcam and a LED attached to a RaspberryPi.
+The device is assumed to have a limited bandwidth towards the server hosting the web app.
+
+== Objective
+
+The demo shows how to use websockets to communicate bidirectionally with an embedded device using standard protocols.
+
+It also shows that it's possible to use Smart.c to develop also the cloud endpoint and expose WebSocket and RESTful APIs
+easy to integreate with modern web stacks.
+
+== How it works
+
+image::docs/arch.png[]
+
+There are two components, once with runs on the device (`device_side`) and one that runs on a stronger machine
+and with more bandwidth (`cloud_side`).
+
+The device app connects to the cloud app via websocket and sends a new jpeg frame as fast as the underlying `raspistill` camera
+grabbing application can handle. The device automatically attempts reconnecting.
+
+The cloud side serves the webapp static pages and serves an MPJEG image on `/mpjg`.
+The MPJEG image handler blocks all the clients until a JPEG frame arrives via websocket
+and then every client will recieve a copy of the frame.
+
+The web app can turn on and off the LED via a RESTful api accessible via the `/api` handler.
+
+== Installation
+
+=== Server side
+
+----
+git clone https://github.com/cesanta/mongoose
+cd mongoose/examples/web_demo
+make cloud_side && ./cloud_side 0.0.0.0:8080
+----
+
+=== Raspberry Pi
+
+The instructions provided here are tailored for the Raspbian distribution.
+
+==== Dependencies
+
+jpegoptim::
+apt-get install jpegoptim
+
+camera::
+run raspi-config and enable camera
+
+==== LED
+
+In order to access the led on your link:http://www.qdh.org.uk/wordpress/?page_id=15[HotPi]
+board you need to export the gpio pins:
+
+----
+for i in 22 23 24; do
+  echo $i >/sys/class/gpio/export
+  echo out >/sys/class/gpio/gpio$i/direction
+  chgrp pi /sys/class/gpio/gpio$i/value
+done
+----
+
+==== Build and run
+
+----
+git clone https://github.com/cesanta/mongoose
+cd mongoose/examples/web_demo
+make device_side && ./device_side yourserver:8080
+----

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <a href="/">demo</a> consists of web app providing access to a webcam and a LED attached to a RaspberryPi.
+The device is assumed to have a limited bandwidth towards the server hosting the web app.</p>
+</div>
+</div>
+</div>
+<div class="sect1">
+<h2 id="_objective">Objective</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>The demo shows how to use websockets to communicate bidirectionally with an embedded device using standard protocols.</p>
+</div>
+<div class="paragraph">
+<p>It also shows that it&#8217;s possible to use Smart.c to develop also the cloud endpoint and expose WebSocket and RESTful APIs
+easy to integreate with modern web stacks.</p>
+</div>

+</div>
+</div>
+<div class="paragraph">
+<p>There are two components, once with runs on the device (<code>device_side</code>) and one that runs on a stronger machine
+and with more bandwidth (<code>cloud_side</code>).</p>
+</div>
+<div class="paragraph">
+<p>The device app connects to the cloud app via websocket and sends a new jpeg frame as fast as the underlying <code>raspistill</code> camera
+grabbing application can handle. The device automatically attempts reconnecting.</p>
+</div>
+<div class="paragraph">
+<p>The cloud side serves the webapp static pages and serves an MPJEG image on <code>/mpjg</code>.
+The MPJEG image handler blocks all the clients until a JPEG frame arrives via websocket
+and then every client will recieve a copy of the frame.</p>
+</div>
+<div class="paragraph">
+<p>The web app can turn on and off the LED via a RESTful api accessible via the <code>/api</code> handler.</p>

+RESTful server with Amazon S3 upload example
+============================================
+
+This example demonstrates how Mongoose could be used to implement a RESTful
+service that uses another RESTful service to handle it's own API call.
+This example takes form data and uploads it as a file to Amazon S3.
+
+## Prerequisites
+
+- Amazon S3 account security credentials: Access Key ID and Secret Access
+  Key ID. Get them from the Amazon IAM console.
+- Amazon S3 bucket.
+
+## Building and running the example
+
+    $ git clone https://github.com/cesanta/mongoose.git
+    $ cd mongoose/examples/restful_server_s3
+    $ make
+    $ ./restful_server_s3 -a ACCESS_KEY_ID -s SECRET_ACCESS_KEY_ID
+    Starting RESTful server on port 8000
+
+Then, open a browser on `http://localhost:8000`
+
+Note: If you're getting a *Temporary Redirect* error, look what is the
+Endpoint value is. It's likely that you have something like
+`BUCKET_NAME.S3_ZONE.amazonaws.com`.
+Change the *Host* field to `S3_ZONE.amazonaws.com and retry`.
+

+
+    <p>
+      This page demonstrates how Mongoose could be used to implement
+      device settings page.</p>
+
+    <h3>How to show device parameters on the page</h3>
+    <p>This page has embedded
+      <code>&lt;!--#call parameter_name --&gt;</code> blocks. For each such
+      block, mongoose triggers <code>MG_EV_SSI_CALL</code> event, passing
+      <code>parameter_name</code> string as an event parameter. A callback
+      then can print some content, which will replace the
+      <code>&lt;!--#call parameter_name --&gt;</code> block.
+      Take a look at <code>handle_ssi_call()</code> to see how that is done.
+    </p>
+
+    <h3>How to save updated values</h3>
+    <p>When Save button is clicked, this page makes Ajax call and passes
+    values to the backend in a POST request. Backend extracts values from
+    the POST request and updates the configuration. Take a look at
+    <code>handle_save()</code> to see how that is done.</p>
+
+
+    <p>You can change values, click Save button, refresh this page - make sure
+    settings values stay intact between refreshes. </p>

-.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.
