title: HTTP Status 902 - No such conversation
body: <p>I was working with a colleague doing some work that involves passing callback URL's from my module to his. Because of some misconfiguration on his side, the call back URL was different and it called a URL from his server, not mine. Appart that we fixed the error, during that misconfigured callback I got this response (which I've never seen before):</p>
  
  <pre><code>HTTP Status 902 - No such conversation
  </code></pre>
  
  <p>Just out of curiosity I googled around and can not find any specification or description of this HTTP status code, and I always thought that status codes only went from 1XX to 5XX (As explained in <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html" rel="nofollow noreferrer">Section 10 of the HTTP 1.1 Spec</a>)</p>
  
  <p>Any idea where I can find an official (or not) spec that describes this?</p>
  
  <p>FYI the server in question is a Tomcat 7.0.25</p>
