An app that I'm writing involves fetching of rss feeds. To get around caching I have been appending ?20080207 (or whatever the 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?

Not without actually doing it, no. You could empty the cache prior to the fetch, though, by calling -[NSURLCache removeAllCachedResponses].
