This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file,
mt-config.cgi, to customize the behavior of the system.
This configuration directive was added in version MT6.2.
When Movable Type is running in a PSGI environment, Movable Type applications will be loaded even if you rename or delete the CGI file. If you want to restrict access to any application, you must set application ID with this directive in mt-config.cgi.
