Scott Mitchell d857b16d76 Http/2 RST_STREAM frame robustness ... Motivation: The Http2ConnectionHandler writeRstStream method allows RST_STREAM frames to be sent when we do not know about the stream and after a RST_STREAM frame has already been sent. This may lead to sending frames when we should not according to the HTTP/2 spec. There is also the potential to notify the closeListener multiple times if the closeStream method is called multiple times. Modifications: - Prevent RST_STREAM from being sent if we don't know about the stream, or if we already sent the RST_STREAM. - Prevent the closeListener from being notified multiple times. Result: More robust writeRstStream logic in boundary conditions.		2015-03-26 11:47:00 -07:00
