Use custom caching

We can overrule the default caching parameters of a site by using "cache" and "expire" parameters in URLs and IWWCM tags.

Custom caching can only be used when a server's default Web Content cache is set to none or advanced caching. If basic caching is used as the default Web Content cache, Custom caching cannot be used.

There are two basic methods in which custom caching can be used with the default server caching settings:

Default Server Caching Enabled

In this scenario, some form of default server caching has been enabled. Caching parameters within connect tags and URLs can be used to either:

  • Disable caching for the data being requested.

  • Apply different caching parameters to the data being requested.

This method is used with sites that are mostly static, but which contain a few dynamic elements that require a different caching strategy from the server's default caching strategy.

Default Server Caching Disabled

In this scenario, default server caching has been disabled. Caching parameters within connect tags and URLs can be used to enable caching for the data being requested.

This scenario is used with sites that contain a large number of elements requiring different caching strategies.

A default caching strategy is setup by an administrator. See Caching options for further information on setting up a default caching strategy.
