+summary: Subscribe to MUC rooms using the HTML5 EventSource API
+...
+
+Introduction
+------------
+
+This module and its docs shamelessly forked from mod_pubsub_eventsource.
+
+[Server-Sent Events](https://en.wikipedia.org/wiki/Server-sent_events)
+is a simple HTTP/line-based protocol supported in HTML5, making it easy
+to receive a stream of "events" in realtime using the Javascript
+[EventSource
+API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).
+
+EventSource is supported in [most modern
+browsers](http://caniuse.com/#feat=eventsource), and for the remainder
+there are 'polyfill' compatibility layers such as
+[EventSource.js](https://github.com/remy/polyfills/blob/master/EventSource.js)
+and [jquery.eventsource](https://github.com/rwldrn/jquery.eventsource).
+
+Details
+-------
+
+Subscribing to a node from Javascript is easy:
+
+    var source = new EventSource('http://muc.example.org:5280/eventsource/myroom');
+    source.onmessage = function (event) {
+      console.log(event.data); // Do whatever you want with the data here
+    };
+
+### Access control
+
+Be warned that this module currently performs no access control. It will expose
+the messages of ALL rooms on the host it is loaded on. This may be changed in
+future revisions.
+
+### Cross-domain issues
+
+The same cross-domain restrictions apply to EventSource that apply to
+BOSH, and support for CORS is not clearly standardized yet. You may want
+to proxy connections through your web server for this reason. See [BOSH:
+Cross-domain
+issues](https://prosody.im/doc/setting_up_bosh#proxying_requests) for
+more information.
+
+Configuration
+-------------
+
+There is no special configuration for this module. Simply load it onto a
+MUC component like so:
+
+    Component "muc.example.org" "muc"
+      modules_enabled = { "muc_eventsource" }
+
+As it uses HTTP to serve the event streams, you can use Prosody's
+standard [HTTP configuration options](https://prosody.im/doc/http) to
+control how/where the streams are served.
+
+**Note about URLs:** It is important to get the event streams from the
+correct hostname (that of the MUC host). An example stream URL is
+`http://muc.example.org:5280/eventsource/myroom`. If you need to
+access the streams using another hostname (e.g. `example.org`) you can
+use the `http_host` option under the Component, e.g.
+`http_host = "example.org"`. For more information see the ['Virtual
+Hosts'](https://prosody.im/doc/http#virtual_hosts) section of our HTTP
+documentation.
