zanque's solution works, but in order to avoid downloading "useless" data, I'd change the http method to HEAD :

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:orinigalURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:15.0];
[request setHTTPMethod:@"HEAD"];
NSURLResponse *response = nil;
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSURL *finalURL = response.URL;
