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 6.1.
When rebuilding templates, Movable Type splits up the rebuilding process into segments, each segment consists of N seconds. The default value for N is 20. So by default, MT returns response to the client when 20 seconds passed since request started. You can change the value globally here; if your web server’s timeout is 60 seconds, you can change to the less than 60.
