Which configuration file do I change in Apache to run it through Tor? I know you use:

Listen 127.0.0.1:8080;

Server_name 127.0.0.1:8080;

I think, but I don't have much experience with web hosting, I know how to use Linux, but a little new to this area and I also heard that Apache can leak out info, any one have any documentation I may read or give some help on preventing that?
