Timeout:
|

Specify read timeout for SPDY frontend
|
||||
connection. Default: 180
|

Specify read timeout for non-SPDY frontend
|
||||
connection. Default: 180

Specify write timeout for both SPDY and
|
||||
non-SPDY frontends.
|
||||
connection. Default: 60
|

|
||||
Specify read timeout for backend connection.
|
||||
Default: 900
|

Specify write timeout for backend
|
||||
connection. Default: 60
|
||||
--backend-keep-alive-timeout=<SEC>
|
||||
Specify keep-alive timeout for backend
|

connection. Default: 60
|
||||
--backend-http-proxy-uri=<URI>
|

Specify proxy URI in the form

a proxy requires authentication, specify

<USER> and <PASS>. Note that they must be

it connects to the backend on behalf of
|
||||
shrpx. This forms tunnel. After that, shrpx
|
||||
performs SSL/TLS handshake with the
|
||||
downstream through the tunnel. The timeouts
|
||||
when connecting and making CONNECT request
|
||||
can be specified by --backend-read-timeout
|
||||
and --backend-write-timeout options.
|
||||

|
||||
Specify read timeout for SPDY frontend
|
||||
connection. Default: 180
|
||||
--frontend-read-timeout=<SEC>
|

--backend-http-proxy-uri=<URI>
|
||||
Specify proxy URI in the form
|

a proxy requires authentication, specify

SSL/TLS:
|
||||
--ciphers=<SUITE> Set allowed cipher list. The format of the
|
||||
string is described in OpenSSL ciphers(1).
|
||||
-k, --insecure When used with -p or --client, don't verify
|
||||
backend server's certificate.
|
||||
--cacert=<PATH> When used with -p or --client, set path to
|
||||
trusted CA certificate file.
|
||||
The file must be in PEM format. It can
|
||||
contain multiple certificates. If the
|
||||
linked OpenSSL is configured to load system
|
||||
wide certificates, they are loaded
|
||||
at startup regardless of this option.
|
||||
--private-key-passwd-file=<FILEPATH>
|
||||
Path to file that contains password for the
|
||||
server's private key. If none is given and
|
||||
the private key is password protected it'll
|
||||
be requested interactively.
|
||||
--subcert=<KEYPATH>:<CERTPATH>
|
||||
Specify additional certificate and private
|
||||
key file. Shrpx will choose certificates
|
||||
used multiple times.
|
||||
--ciphers=<SUITE> Set allowed cipher list. The format of the
|
||||
string is described in OpenSSL ciphers(1).
|
||||
-k, --insecure When used with -p or --client, don't verify
|
||||
backend server's certificate.
|

--cacert=<PATH> When used with -p or --client, set path to

linked OpenSSL is configured to load system
|
||||

|
||||
--private-key-passwd-file=<FILEPATH>
|
||||
Path to file that contains password for the
|
||||
server's private key. If none is given and
|
||||
the private key is password protected it'll
|
||||
be requested interactively.
|
||||
--subcert=<KEYPATH>:<CERTPATH>
|
||||
Specify additional certificate and private
|
||||
key file. Shrpx will choose certificates
|
||||
based on the hostname indicated by client
|
||||
using TLS SNI extension. This option can be
|
||||
used multiple times.
|
||||
|
||||

|
||||

||||
Sets the initial window size of SPDY
|
||||
backend connection to 2**<N>.

|
||||
Default: 100
|

|
||||
backend connection to 2**<N>.
|
||||
Default: 16
|
||||
--backend-spdy-no-tls
|
||||
Disable SSL/TLS on backend SPDY connections.
|
||||
SPDY protocol must be specified using
|
||||
--backend-spdy-proto
|
||||
--backend-spdy-proto
|
||||
Specify SPDY protocol used in backend
|
||||
connection if --backend-spdy-no-tls is used.

|
||||
|
||||
Mode:
|
||||
-s, --spdy-proxy Enable secure SPDY proxy mode.

||||
--spdy-bridge Communicate with the backend in SPDY. Thus
|
||||
the incoming SPDY/HTTPS connections are
|
||||
converted to SPDY connection and relayed to
|
||||
the backend. See --backend-http-proxy-uri
|
||||
option if you are behind the proxy and want
|
||||
to connect to the outside SPDY proxy.
|
||||
--client Instead of accepting SPDY/HTTPS connection,
|
||||
accept HTTP connection and communicate with
|
||||
backend server in SPDY. To use shrpx as
|
||||
a forward proxy, use -p option instead.
|
||||
-p, --client-proxy Like --client option, but it also requires
|
||||
the request path from frontend must be
|
||||
an absolute URI, suitable for use as a
|
||||
forward proxy.
|
||||
-s, --spdy-proxy Enable secure SPDY proxy mode.
|
||||

|
||||
accept HTTP connection and communicate with
|
||||
backend server in SPDY. To use shrpx as
|
||||
