I'm guessing you only have one available 'real' IP address to work with, 
right?

Two thoughts come to mind, but I'm sure there are other ways.

1) There's an 'experimental' plugin for iptables that can examine 
packets for arbitrary text.  I forget what it's called, and it may even 
be part of the standard package now.  I can't find my reference to it at 
the moment. Sorry.

2) Use mod_rewrite to handle it.  However, you'll have to change the 
port when redirecting traffic to the 2nd server if you have only one IP.
