// The basics:
// - Write your own NSURLProtocol subclass and register it.
// - Override the 5 required methods
// - Kick off download or cache fetch during |startLoading|
// - Update self.client with progress/completion/failure notifications.

// UIWebView will download requests concurrently via NSURLProtocol.
// If you use the typical NSURLCache hook to download content, you're
// stuck with serial downloads.
