Really sounds like what you are looking to do is configure a reverse
proxy, and with rewrite capability.  Do a search for reverse proxy on
the net, if you haven't done so.

I have tried this, with limited success.  Very limited.  A static web
page, and a few with PHP worked fine, but anytime the system encountered
Java*, it was done.  Also, clicking on some links would redirect them to
the real site, instead of through the proxy, which of course is not what
you want.  Also, even some non-Java enabled pages just looked really
weird in the set up.

Squid is probably not what you will want to use, unless things have
changed recently.  When I had my dinky little reverse working, it was
with Apache in proxy mode, with mod_proxy, mod_proxy_rewrite (I think
this is what it was).

We were trying to allow students access to paid databases that were only
accessible from internal machines.  A product was offered that cost $$,
but was simple to set up and let run.  It was called EZProxy.  I'd say
buy it, because I spent most of two weeks hacking at this problem at
work, only to get the poor results stated above. 

Unless you are really hell-bent on rolling your own...

Yes, it runs on Linux.
