intercepting TCP?

[Bill Ataras]

Does anyone know of a way on linux running ip_masq/ip_chains to grab all
TCP connections outgoing toward a port 80 on any IP and forward them to
some other IP/port? I'm looking for a way to insert myself into raw HTTP
conversations to do transforms/etc. without the app knowing about it. Or
perhaps a windows tool to do the forwarding from the machine running IE?
Also, doing a proxy server thing isn't sufficient.

Thanks

moding tomcat to be a proxy server

[Bill Ataras]

Google doesn't give me much. I've gotten good results in a few hours so
far (I'm browsing with it now:) writing a valve that passes through http
traffic using the host field and filtering some headers. Takes advantage
of all the coyote connection/http11/thread stuff. Installs in
StandardEngine via server.xml config and doesn't pass the request to
invokeNext() so no need to config context/host etc.

I'm wondering if anyone has used tomcat in this way for real (beyond a
few hours of mucking around).

Personally, I would write the proxy as the Coyote adapter. That should 
faster as you can use reusable buffers instead of manipulating String 
objects. Your solution would work fine, though :)

Add in LB and a caching engine, and that's a feature we'd be very happy 
if you contributed :)
