A good way to figure out what is going on is to set up a proxy for the
client. That way you have a trace of exacly what URLs the client requests.

The most common problem in reverse proxies is that servers have a real bad
habit of giving absolute URLs to the client, forcing them to go directly
to the URL the server thinks is the correct URL for himself, which may be
quite different from what the client should actually be going to via the
reverse proxy.
