How to download a large file with the iPhone SDK and avoid memory usage issues?

connectionDidFinishLoading called before didReceiveData with rails production sending photos

I have a rails 3.0.3 website that, in development mode, responds to a HTTP GET by calling didReceiveData and then connectionDidFinishLoading, and photo data is sent from the website to the iPhone and displayed correctly.

I'm using carrierwave to handle the photos for both the development and production rails sites.
