It’s possible to assign multiple protocols to a single site by specifying bindings that have different protocol schemes. It’s also possible to…

As far as I can tell there has never been a description of what the mysterious LegacyExtendedProtectionPolicy property is for that appeared on the HTTP and TCP transports and is now slowly in the process of disappearing.

Fix for HTTP Startup Hang

The http.sys driver is configured to automatically start so that it can…
