Correct me if I'm wrong, but you want tux to work as a proxy in reverse
mode? If that is so, I'm not sure tux can do that. An alternative would
be the following:

1. Configure tux as the main web server to serve static content.
2. Configure squid as a reverse proxy and use it as the clientport.
3. Have squid forward requests to apache (on another port) and apache
set the right cache control headers so squid can do the right caching.

Not sure if it will work, but I don't see why not. There might be some
issues as:

1. More services running might actually increase the load on your
server.
2. Increased administrative overhead (more software to configure,
upgrade, monitor, etc.)
