  The cache module contains examples.  You can configure it to cache specific attributes.

  Read the comments in mods-available/cache.  Look for the comments around "update".

  I'm aware of that,

  You need to set the various cache attributes before calling the cache module.  See the comments at the end of the cache module for documentation.

  When checking the cache:

	update {
		&control:Cache-Status-Only = yes
	}
	cache
	if (ok) {
		# cache entry was found
	}

  When updating the cache:

	cache

  It's that simple.
