I worked with a colleague doing some work, which involves passing the callback URL from my module to it. Due to an incorrect configuration on his side, the callback url was different and he called the url from his server, not mine. Appart, that we fixed the error, during this incorrectly configured callback I received this answer (which I had never seen before):
HTTP Status 902 - No such conversation
Just out of curiosity, I googled around and cannot find any specification or description of this HTTP status code, and I always thought that status codes are only 1XX to 5XX (As explained in Section 10 of the HTTP 1.1 specification
Any idea where I can find the official (or not) spec that describes this?
The FYI server in question is Tomcat 7.0.25
EDIT: Including response image
