By default, nghttp2 library only handles HTTP/2 frames and does not recognize first 24 bytes of client connection preface. This design choice is done due to the fact that server may want to detect the application protocol based on first few bytes on clear text communication. But for simple servers which only speak HTTP/2, it is easier for developers if nghttp2 library takes care of client connection preface. If this option is used with nonzero val, nghttp2 library checks first 24 bytes client connection preface. If it is not a valid one, nghttp2_session_recv() and nghttp2_session_mem_recv() will return error NGHTTP2_ERR_BAD_PREFACE, which is fatal error. |
