This function is useful for the client application to know that there
is a chance that request can be sent. If this function returns 0,
there is zero chance to make a request.
This commit also set error_code passed to
nghttp2_on_stream_close_callback to NGHTTP2_REFUSED_STREAM if request
is not sent.
The control process handles signals, reads configuration, reads
private keys, and bind port (which may be privileged one). It never
drop privileges, so that it can execute new binary with the same
privilege. It forks worker process. The worker process handles all
incoming connections. It drops privilege.
The intention of this stream API is give server application about
stream dependency information, so that it can utilize it for better
scheduling of stream processing. We have no plan to add object
oriented API based on stream object.
The overall meaning is the same. I added a paragraph to introduce nghttp2_hd_inflate_hd(), and added an explanation of using NGHTTP2_NV_FLAG_NO_INDEX for security sensitive headers.
The overall meaning of the tutorial is the same. I added text describing frame types where it helps explain the callbacks better, e.g. introducing the HEADERS frame before on_header_callback().
Also fixed a couple of typos:
- Fixed ``reacb`` typo to ``readcb``
- Added parens to some functions, e.g. ``on_frame_recv_callback`` => ``on_frame_recv_callback()``
The overall meaning of the tutorial is the same, except for a couple of changes:
- app_context struct was called "app_content", fixed the typo
- nghttp2_session_server_new2() is mentioned, but the example uses nghttp2_session_server_new() instead, changed the text to match
