Just curious, why try and get around caching? Caching is usually there
for good reason. For example a 304 would mean "not modified" (use your
cache instead) so you can usually depend on the data you have stored
locally.

An app that I'm writing involves fetching of rss feeds. To get

current date is) to the URL. Unfortunately some server's don't like
this and will return a 404. Is there a way using cocoa to determine
if a URL will return a 404?
Any tutorials or howtos will be of great help and appreciated.
Thanks,
