Receive HTTP Headers via NSURLRequest/NSURLConnection in Cocoa

I've been working on figuring out how to receive HTTP Headers via a request made with NSURLConnection. Typically a request is made with something as simple as the following:

    NSURLConnection *connection = [[NSURLConnection alloc]     initWithRequest:request         delegate:self]; 

The only way I've personally found in Apple's abundant documentation to receive response headers is via a synchronous call using the following NSURLConnection class method:

+ (NSData *)sendSynchronousRequest:(NSURLRequest *)request returningResponse:(NSURLResponse **)response error:(NSError **)error 

Here I can easily reference a response object of type NSURLResponse. The problem here is that I'm not ready to make synchronous requests via a mobile device, especially with a network that has high latency such as EDGE. Is it possible to get similar results with the default, asynchronous behavior of NSURLConnection?

Prompting and Delegate question
In your connection delegate, add the -connection:didReceiveResponse: method. Results for performSelector: differ from standard dot notation call?If you're doing a standard HTTP request, the NSURLResponse object passed in will actually be an NSHTTPURLResponse object, and responds to the -allHeaderFields message.
