<p>When you authenticate to the XMPP server on your backend application (for
example a BOSH client in Django), you’ll receive two tokens, RID (request ID) and SID (session ID).</p>

example via a BOSH client in Django), you’ll receive two tokens, RID (request ID) and SID (session ID).</p>
<p>The <strong>Session ID (SID)</strong> is a unique identifier for the current <em>session</em>. This
number stays constant for the entire session.</p>
<p>The <strong>Request ID (RID)</strong> is a unique identifier for the current <em>request</em> (i.e.
page load). Each page load is a new request which requires a new unique RID.
The best way to achieve this is to simply increment the RID with each page
load.</p>
<p>When you initialize converse.js in your browser, you need to pass it these two
tokens. Converse.js will then use them to attach to the session you just
created.</p>
<p>You can embed the RID and SID tokens in your HTML markup or you can do an
XMLHttpRequest call to your server and ask it to return them for you.</p>
