corgi is a CGI server.

corgi listens on port 26744 by default.

/etc/corgi.conf

Server
    Port 26744

Script <path-to-cgi-script>
    Match
        Regex <regular-expression>

Script <path-to-cgi-script>
    Environment
        HTTP_HOST <hostname>
        ENV_KEY <some-env-value>

See corgi.conf for the configuration I use with my cgit instance.

Scripts are tried in order, looking for one that matches. If none match, the first script is ran.

Sets the following environmental variables for the CGI script, many following RFC 3875:
- GATEWAY_INTERFACE to the fixed value CGI/1.1
- PATH_INFO to the HTTP path the client requested
- QUERY_STRING to the query part of the URI
- REMOTE_ADDR is the Forwarded-For header, maybe prefixed with an X-, or the client address if that header is not set
- REQUEST_METHOD to the HTTP request method
- SCRIPT_NAME is set to the path specified in the config
- SERVER_NAME is set to the HTTP host header
- SERVER_PORT is the port that corgi is running on
- SERVER_PROTOCOL is the HTTP version string that the request came in on
- SERVER_SOFTWARE is corgi/1.0 where 1.0 is the current version number

Additionally, corgi will set environment variables for the HTTP request headers. They will be uppercased and hyphens replaced with underscores.

Any environmental variable may be overridden if it is set in the configuration file, except the CONTENT_LENGTH envar.
