There was a problem hiding this comment.
We can probably add a cancellation test here as well. Set the handshake timeout to something small like 1 millisecond and check that the request was canceled.

Problem
HttpsConnectionMiddleware carefully considers a handshake timeout.
New TlsListenerMiddleware does not use it, and in case of a configured timeout request will not be cancelled.
Solution
I renamed
TlsListenerMiddlewaretoTlsListenerto be used as part ofHttpsConnectionMiddleware. It will use the same cancellation token as the latter. We can move the code directly intoHttpsConnectionMiddlewarebut IMOTlsListenerhas a bit different purpose and can be living in a separate instance.TlsListenernow does not invoke next middleware delegate.Also changed the parsing code to remember the TLS client hello record length, and if that is known re-parsing of TLS client hello "header" will not be happening on each iteration.
Closes #62172
