Async Pluggable Protocol Handler: Forward to other protocol?

Question

When implementing an asyncrhonous plauggable protocol handler, is it possible to "redirect" the implementation to another protocol?

Instantiating the protocol handler for another protocol (such as file: or res:) looks a bit scary and not intended.

Answer 1

调用IInternetProtocolSink::ReportResult ，将第一个参数传递给INET_E_REDIRECT_FAILED ，最后一个传递所需的URL（第二个参数无关紧要； 302会是一个很好的选择）。

Answer 2

I used IInternetProtocolSink::ReportProgress(BINDSTATUS_REDIRECTING, pszRedirURL) from IInternetProtocolRoot::Start , and then simply redirected everything to pszRedirURL protocol's IInternetProtocol . As I mentioned in the comments, that worked for IE6. A lot of IE internals has changed since then.
