You can set HTTP fields with an NSMutableURLRequest:

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:@"Your string" forHTTPHeaderField:@"If-Modified-Since"];
// ...

You can then check the status code of the response and look specifically for 304 (Not Modified).
