This is an implementation of a RESTs transport for the Janus API, using the libmicrohttpd library (http://www.gnu.org/software/libmicrohttpd/). This module allows browsers to make use of HTTP to talk to the Janus core. Since a Janus instance may be deployed on a different domain than the web server hosting the web applications using it, the plugin automatically handles OPTIONS request to comply with the CORS specification. POST requests can be used to ask for the management of a session with the server, to attach to a plugin, to send messages to the plugin itself and so on. GET requests instead are used for getting events associated to a Janus session (and as such to all its plugin handles and the events plugins push in the session itself), using a long poll approach. A JavaScript library (janus.js) implements all of this on the client side automatically.

Note
  There's a well known bug in libmicrohttpd that may cause it to spike to 100% of the CPU when using HTTPS on some distributions. In case you're interested in HTTPS support, it's better to just rely on HTTP in Janus, and put a frontend like Apache HTTPD or nginx to take care of securing the traffic. More details are available in Deploying Janus.
