Concurrent HTTP POST requests on different HTTP2 concurrent streams require that the client's header_capture_context is re-used to capture headers on a second stream before all of the body data has been received (and sent to the application) on the first stream. As a result, any captured headers must be sent to the application callback before any headers can be received on a different stream. In practice this means that for HTTP2 the application callback is called for the first time on receiving a headers frame, before any data frames are received. All subsequent application callbacks will not include the request header data. While this mechanism is not necessary for HTTP1, it is also updated to only send headers in the first application callback for consistency.
