Fixes #31254
Fixes #110577
There are race conditions in HTTP 1.1 response stream reading methods that may prevent the exceptional termination of those methods despite cancellation callbacks firing and disposing the connection, see the discussion starting with #31254 (comment).
As a result, these methods may call
CompleteResponsereturning the disposed connection to the pool.This is a minimal fix for the mentioned issue, but I agree with @MihaZupan that we should rework the HTTP/1.1 cancellation, making sure to forward the CancellationTokens down to the underlying stream instead of relying on CancellationTokenRegistration + Dispose. In case we take this PR, I'm planning to open a new issue to track that work.
