I can't, but I'm glad you posted this! A friend just took over a site I had been hosting and after he uploaded all the files and added the domain to his account (and stopped getting 'bad httpd conf' errors) he pronounced it working - yet ... I am still not able to load the site in IE or Firefox, even after mutiple cache clearings. I just used the URL without the www and darned if that doesn't work just fine. He says the site is also set up to accept BOTH (that's the default domain setup, if I recall).
Hmm, I wonder if there's some DNS caching going on between my work PC and DH? Maybe since I never used the non-www address before, that one's not cached so it gets resolved by DH DNS, while the www version has to age out of some intermediate cache somewhere ???
