问题 I'm trying to play a mp4 video on my server and I'd like to cache this video to disk simultaneously. I know that I can just use 2 requests to do this, one for download another one created by AVPlayer to play the video, but this will waste the network bandwidth. So I need to use just one outer request to download the data and capture all NSURLRequest from AVPlayer in MyNSURLProtocol and manually create NSHTTPURLResponse for them.
