By default, when caching is enabled, a default cache rule is put into place that caches
objects based on default settings. Additional caching rules can be configured by clicking
on the Create a Cache Rule link in the Tasks tab. Each rule created can contain the following
customizations:
. Source and destination networks
. What types of items are retrieved and stored in the cache
. HTTP caching settings, such as the Time to Live (TTL) of objects retrieved
. File Transfer Protocol (FTP) caching settings
. Secure Sockets Layer (SSL)??“specific settings
. Object size limitations
Just as with firewall rules, caching rules are applied in order, from top to bottom, until a
match is made. Through the creation of multiple caching rules, fine-grained control over
the caching settings of the clients can be achieved.

internal clients.
