If I packet-trace this, will I find that Safari is barfing on a simple 302 redirect?
Safari can’t open the page “http://www.twitter.com/”. The error was: “Operation could not be completed. (kCFErrorDomainCFNetwork error 302.)” (kCFErrorDomainCFNetwork:302) Please choose Report Bugs to Apple from the Safari menu, note the error number, and describe what you did before you saw this message.
