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

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].
Have tried this, though it still produces the same results. Plus the
code I'm running is inside a thread detached from the main thread and
thus that function doesn't achieve the desired result.
Could you please expand on what you mean by "Not without actually
doing it"? Do you mean not without retrieving the file?
Is there an easy way of using either NSURLRequest or NSURLResponse to
see if there will be a file returned instead of a 404?
Thanks,
