Chapter 8: Enabling and Customizing Caching

HAPTER

NABLING

AND

USTOMIZING

ACHING

You can enable caching as the device defaults or enable caching for specific Scanning Servers. When

caching is enabled, content is stored in the Server for future use, thereby speeding up performance

time.
Before enabling cache the pre‐requisites of installing the

Caching

Kit

with the relevant licenses

must be completed.

If you do enable caching, you must then ensure that appropriate caching policy is set.
By default, when caching is enabled, all content is cached. But you can use Caching policies to bypass

caching or to determine which URLS or File extensions are cached.
This chapter contains the following procedures:
•

Enabling Caching

•

Defining a Caching Policy

•

Defining a Rule in a Caching Policy

•

Defining Conditions in a Caching Rule
