Re: [Exist-development] Problem with XQuery URL Rewrite behind reverse proxy

[Adam R. <ad...@ex...>]

Okay I have managed to get around to finally fixing the issues I was
experiencing. The problem was not with the server name itself. I use
nginx as my reverse proxy and I can configure nginx to correctly pass
the server name directly to eXist in the proxied request by setting -

proxy_set_header        Host                    $host;

There was then an issue with the server-name checks you can setup in
controller-config.xml when searching for controller.xql files. I have
now fixed these as revision 12650.

Cheers Adam.
