NSURLProtocols can be used with WebView and UIWebView to load content from custom protocols. These protocols have the ability to generate redirects by calling -URLProtocol:wasRedirectedToRequest:redirectResponse: on their NSURLProtocolClient. The following assertion failure occurs when this is done in a debug build of WebKit:
