Unfortunately, this isn't possible. As Richard Dingwall already suggested, you could create a TCP listener and use that port. This approach has two possible problems:

• In theory a race condition may occur, because another TCP listener might use this port after closing it.
• If you're not running as an Administrator, then you need to allocate prefixes and port combinations to allow binding to it. This is impossible to manage if you don't have administrator privileges. Essentially this would impose that you need to run your HTTP server with administrator privileges (which is generally a bad idea).
