[users at bb.net] buildbot behind reverse proxy under URL prefix

[Josh Bialkowski]

Thanks Andreas,

I've got it working now. There are a couple of things going on but the
primary issue was a false assumption on my part. I had configured nginx to
forward absolute URIs through the proxy, and I was looking for the correct
way to prefix buildbot URLs with "buildbot/". I think the latter is not
possible. Instead, I guess the correct thing to do is forward *relative*
URIs through the proxy.

In terms of nginx config this means:
proxy_pass http://localhost:8083/;
instead of
proxy_pass http://localhost:8083;
The subtle difference being the trailing backslash.
