Hello all,

I run nginx on port 80 in front of apache with mod_backhand on port 81 on the
same machine, which does the load balancing across backend apache servers.

Our application makes a redirect on a few rarely visited places and there apache
generates a redirect in the form of http://domain:81/place/to/go. Thats get fed
to the client, which sees a "connection refused" because of the closed 81 port.

What is the right way to fix this?

Obviously I need to rewrite that :81 somewhere into :80 or throw it away
alltogether. I just don't understand the http proxying fully enough to see the
solution. I think I either need some RewriteEngine magic on apache side or some
proper rewrite statement on nginx side.

Thanks for help,
