Getting the reponse body of a 302 HTTP redirect with NSURLConnection

Question

I'm sending a HTTP GET request to an URL using NSURLConnection with the delegate. The request gets redirected with a HTTP 302 and the new request is performed and the data retrieved.

The problem is that I don't want the body of the redirected HTTP request but the content of the original redirect response.

I've implemented - (NSURLRequest *)connection:(NSURLConnection *)connection willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)response which is called with the redirectRepsonse but connection:didReceiveData is not called until the new redirected request returns.

I've found no solution so far except of using a CFNetwork based approach.

Update: I've created a sample project with the problem for you to play with: https://github.com/snod/302RedirectTest

Any ideas?

Answer 1

From the docs of -connection:willSendRequest:redirectResponse: :

To receive the body of the redirect response itself, return nil to cancel the redirect. The connection continues to process, eventually sending your delegate a connectionDidFinishLoading or connection:didFailLoadingWithError: message, as appropriate.
