Whenever we try to access http://www.cnn.com web site through the
proxy server it just stalls. No error message, nothing.

However, we can access http://edition.cnn.com without any problems.
As far as I can tell, http://www.cnn.com and http://edition.cnn.com
are the exact same web site just different web servers.

If I configure my browser to bypass the proxy server,
http://www.cnn.com comes up just fine. That makes me think the
problem is in the cache.

Would re-loading the proxy service be the best way to resolve this?
