Usage: nghttpd [OPTION]... <PORT> [<PRIVATE_KEY> <CERT>]
HTTP/2 server
<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.
--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: 100
-n, --workers=<N>
Set the number of worker threads.
Default: 1
-e, --error-gzip
Make error response gzipped.
--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>

extensions that represent them.

--version Display version information and exit.
-h, --help Display this help and exit.

The <SIZE> argument is an integer and an optional unit (e.g., 10K is
10 * 1024). Units are K, M and G (powers of 1024).
