Hello,

there is a new module named xhttp which provides an embedded http server inside the SIP server. It reuses the transport layer from the core, so you can send http requests via TCP and TLS. The port is the same as for SIP traffic. The documentation of the module is available at:

http://sip-router.org/docbook/sip-router/branch/master/modules/xhttp/xhttp.html

Since sip and http are very similar, you can use other modules in handling the http requests. For example, you can do www-authentication:

event_route[xhttp:request] {
    if (!www_authorize("xcap", "subscriber"))
   {
         www_challenge("sip-router.org", "0");
         exit;
    }
    xhttp_reply("200", "OK", "text/html",
          "<html><body>Welcome $au, you are connected from $si:$sp</body></html>");
}

allowing in this way only local SIP users to do http requests.

For now supports only http 1.0, meaning it cannot take chunked requests (usually happening in PUT requests with large body). Hope it is useful for some of you. Its main goal right now is to offer the transport layer for embedded xcap server (the new xcap_server module), but it can be used for service monitoring, server control, etc.

Cheers,
Daniel
