Apache mod_fcgid
My HostingUK hosting service runs this module and I have seen notices and warnings in my server logs
The mod_fcgid is the means by which CGI scripts are run on an Apache web server.
CGI stands for Common Gateway Interface.
What Apache say:
The reason for this page as the reference to mod_fcgid was in the message seen in my server logs when the Timezone was not set correctly in a PHP script.
What Dave at Cardif University says:
In other words the script could be written in Perl, Python, PHP or another scripting language.
You can also use a SSI (Server Side Include) to run the same actions as a CGI script.
