CacheControl

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.

Specifies the Cache-Control value for the Admin screen. The value specified for this configuration directive is added to the HTTP response and can be used to specify how the content cache for the Admin screen is controlled.

This configuration directive is useful when you want to control how cache data is handled, such as when an operational security policy requires preventing cache retention on external servers like proxy servers.

Note that Cache-Control is effective with HTTP protocol version 1.1 or later. For more details on Cache-Control, see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9

If a value is set for the configuration directive ForceCacheControl (formerly HeaderCacheControl), a Cache-Control header is always added to the response and the specified value is returned. In contrast, the configuration directive CacheControl adds a Cache-Control header together with a Pragma header and returns the specified value.

Note: If either the configuration directive HeaderCacheControl or ForceCacheControl is set, the value specified for CacheControl is ignored.
