Getting the URLs right when proxying to apache and mongrel

[marc]

Hi,

I'm testing nginx by putting it in front of an existing Apache server, 
and also using it to serve rails via mongrel.

This works okay, mostly, but for a couple of things:

1. When I proxy to Apache (on port 81) the URLs are written showing the 
port, e.g.

  http://mote:81/Main/Software

I'd like not not to see the port number, if possible,

I tried using

    upstream apache {
      server mote:81;
    }

and 

    location / {
        proxy_pass   http://apache;
    }

but that resulted in URLs of the form: http://apache/...

2. The url required to access the rails app fails without the trailing 
slash. So,
  
  http://mote/rails/

works, but the following doesn't

  http://mote/rails

I'd like the latter to work, if possible,

I've added my conf file below for reference.
