It looks like you're going through a proxy server. Maye be that's why LWP::UserAgent didn't work. You shouldn't try to make it work however if that means you need to put some proxy information in the script. It's not considered a good security practice.
On IE browser, you may go to Tools > Internet Options > Connections > LAN Settings to see if in fact you're using a proxy. On Netscape or Mozilla, Edit > Preferences > Advanced > Proxies.
If you use AOL like that, all the web contents are cached on the server side and you can do nothing about it.
Should you post for further help, remember DON'T post your proxy settings on the web. It could be risky.
