export SCRIPT_FILENAME=/status
 
if <a class="red-text disabled"></a>
then
        export QUERY_STRING+="full&"
fi
if <a class="red-text disabled"></a>
then
        export QUERY_STRING+="json&"
fi
 
export REQUEST_METHOD=GET
 
CGI2FCGI=/usr/bin/cgi-fcgi
 
if [ ! -x ${CGI2FCGI} ]

        echo "cgi-fcgi does not appear to be installed:"
        echo -e "\t* On debian this can be installed with: $ sudo apt-get install libfcgi0ldbl\n"
        exit 1
fi
 
if [ ! -S ${LISTEN} ]
then
        echo "${LISTEN} does not appear to be a socket"
        exit 1

${CGI2FCGI} -bind -connect ${LISTEN}
