HTTP/2 allows sending the payload in both directions gradually, until a frame with an END_STREAM flag closes a direction. The BIG-IP does not properly handles an early response from a server when HTTP router is configured on a virtual and partial payload sent in each direction. In this case, communication over the stream hangs.
A response with a partial payload is not delivered to a client. Communication freezes on that specific stream.
-- Virtual server is configured on the BIG-IP system with HTTP and HTTP/2 profiles on both the client and server sides. -- HTTP router profile is configured on the virtual server. -- Client sends a request and delivers a partial payload, waiting for a response from a server. -- Server responds with a partial payload.
