NSURLRequest + NSHTTPURLResponse is clearly the way to role. How do I just grab the header info?

Calling allHeaderFields on your NSHTTPURLResponse will return them as a dictionary.

[response allHeaderFields]

where response is your NSHTTPURLResponse object.

Additionally, using an NSMutableURLRequest and calling [request setHTTPMethod:@"HEAD"] will result in less bandwidth being used (if the server supports it) – rpetrich Aug 30 '09 at 11:35

rpetrich, This is the critical bit I was looking for. I DON'T want to grab the entire message body of the URL which is many gigabytes. Thanks so much for the pointer. Cheers, Doug – dugla Aug 30 '09 at 12:23

⌘-doubleclick on a reference to "NSHTTPURLResponse" in your code, and it will show you the documentation.

That doesn't show the documentation, it just links to the header file with the method signature. – PostCodeism Apr 21 '11 at 16:53
