Hi, I was wondering if there is a special reason why the ResponseSent and ReceiveRequestBytes hooks don't have suspending handlers? At least the latter is given a ByteReadChannel so suspending calls should be quite common?

Hey @Andreas Scheja, thanks for the question. Could you tell me why do you need suspension in ResponseSent ?

As for ReceiveRequestBytes, we can add suspension there. I made a ticket: https://youtrack.jetbrains.com/issue/KTOR-5406/Add-suspend-modifier-to-ReceiveRequestBytes-hook

@e5l I have no use case where I would need it for ResponseSent right now, but is there a compelling reason not to change it? I mean if you want to call something suspending in there (and can't just launch it in a fire-and-forget manner) you have to bridge it with runBlocking, which would block the thread of the coroutine calling the hook -> not a good solution for a busy server.
