+ <PORT> Specify listening port number.
+ <PRIVATE_KEY>
+ Set path to server's private key. Required unless
+ --no-tls is specified.
+ <CERT> Set path to server's certificate. Required unless
+ --no-tls is specified.
+Options:
+ -a, --address=<ADDR>
+ The address to bind to. If not specified the default IP
+ address determined by getaddrinfo is used.
+ -D, --daemon
+ Run in a background. If -D is used, the current working
+ directory is changed to '/'. Therefore if this option
+ is used, -d option must be specified.
+ -V, --verify-client
+ The server sends a client certificate request. If the
+ client did not return a certificate, the handshake is
+ terminated. Currently, this option just requests a
+ client certificate and does not verify it.
+ -d, --htdocs=<PATH>
+ Specify document root. If this option is not specified,
+ the document root is the current working directory.
+ -v, --verbose
+ Print debug information such as reception/ transmission
+ of frames and name/value pairs.
+ --no-tls Disable SSL/TLS.
+ -c, --header-table-size=<SIZE>
+ Specify decoder header table size.
+ --encoder-header-table-size=<SIZE>
+ Specify encoder header table size. The decoder (client)
+ specifies the maximum dynamic table size it accepts.
+ Then the negotiated dynamic table size is the minimum of
+ this option value and the value which client specified.
+ --color Force colored log output.
+ -p, --push=<PATH>=<PUSH_PATH,...>
+ Push resources <PUSH_PATH>s when <PATH> is requested.
+ This option can be used repeatedly to specify multiple
+ push configurations. <PATH> and <PUSH_PATH>s are
+ relative to document root. See --htdocs option.
+ Example: -p/=/foo.png -p/doc=/bar.css
+ -b, --padding=<N>
+ Add at most <N> bytes to a frame payload as padding.
+ Specify 0 to disable padding.
+ -m, --max-concurrent-streams=<N>
+ Set the maximum number of the concurrent streams in one
+ HTTP/2 session.
+ Default: )"
+ << config.max_concurrent_streams << R"(
+ -n, --workers=<N>
+ Set the number of worker threads.
+ Default: 1
+ -e, --error-gzip
+ Make error response gzipped.
+ -w, --window-bits=<N>
+ Sets the stream level initial window size to 2**<N>-1.
+ -W, --connection-window-bits=<N>
+ Sets the connection level initial window size to
+ 2**<N>-1.
+ --dh-param-file=<PATH>
+ Path to file that contains DH parameters in PEM format.
+ Without this option, DHE cipher suites are not
+ available.
+ --early-response
+ Start sending response when request HEADERS is received,
+ rather than complete request is received.
+ --trailer=<HEADER>
+ Add a trailer header to a response. <HEADER> must not
+ include pseudo header field (header field name starting
+ with ':'). The trailer is sent only if a response has
+ body part. Example: --trailer 'foo: bar'.
+ --hexdump Display the incoming traffic in hexadecimal (Canonical
+ hex+ASCII display). If SSL/TLS is used, decrypted data
+ are used.
+ --echo-upload
+ Send back uploaded content if method is POST or PUT.
+ --mime-types-file=<PATH>
+ Path to file that contains MIME media types and the
+ extensions that represent them.
+ Default: )"
+ << config.mime_types_file << R"(
+ --no-content-length
+ Don't send content-length header field.
+ --ktls Enable ktls.
+ --no-rfc7540-pri
+ Disable RFC7540 priorities.
+ --version Display version information and exit.
+ -h, --help Display this help and exit.
