I'm trying to connect to localhost through my browser to learn some apache tomcat stuff. When I tried to connect to localhost through Firefox, I couldn't; when I tried through IE, I could the first time, but not after that. I'm using Windows 7, and changed the hosts file to point localhost to 127.0.0.1. I can successfully ping localhost and 127.0.0.1. I have tried turning off my antivirus and my Windows Firewall, but to no avail. What am I doing wrong?
