I don't know how to fix NSURLConnection, but an alternative would be to use the source to some other HTTP client. By having the source code, you would have full control over the buffering. For example, libcurl is available under the MIT License: http://curl.haxx.se/libcurl/ That would probably be the easiest route. You should file a bug with Apple at http://bugreport.apple.com/ Buffering a lot of data isn't a big deal on Mac OS X, but it's bad news on an embedded device like the iPhone.
