Configure > Using CGI
Starting from version 1.7, H2O comes with a FastCGI-to-CGI gateway (
fastcgi-cgi), which can be found under
share/h2o directory of the installation path.
The gateway can be used for running CGI scripts through the FastCGI handler.
The example below maps
.cgi files to be executed by the gateway.
It is also possible to run CGI scripts under different privileges by specifying the
user attribute of the directive.
file.custom-handler: extension: .cgi fastcgi.spawn: command: "exec $H2O_ROOT/share/h2o/fastcgi-cgi"
$ share/h2o/fastcgi-cgi --help Usage: share/h2o/fastcgi-cgi [options] Options: --listen=sockfn path to the UNIX socket. If specified, the program will create a UNIX socket at given path replacing the existing file (should it exist). If not, file descriptor zero (0) will be used as the UNIX socket for accepting new connections. --max-workers=nnn maximum number of CGI processes (default: unlimited) --pass-authz if set, preserves HTTP_AUTHORIZATION parameter --verbose verbose mode
