almost. The code I posted does work, for the case I tested.
There is one other NSURLConnection callback to handle,
that covers URLs that redirect.
There is additional complexity with NSURLCredentials, if you are trying
to access a password protected website, or the user is behind a
password-protected proxy.
There is additional complexity if you are doing HTTP PUTs or HTTP POSTs
to a URL that you haven't previously done an HTTP GET from, and that
URL redirects.
If you want to see code that handles all of these cases, take a look at
the GDataHTTPFetcher code in Greg Robbins' GData Objective C library.
