6. Under Security Server Cache settings, click to enable the Security Server Policy
Store Cache, Security Server Authorization Cache, or ColdFusion Server Cache if
you want ColdFusion to cache security information and transactions on the
security server.
See "Caching Advanced Security Information" on page 300 for a description of the
Advanced security caches.
You can also change the Refresh Interval setting for any of the caches. This
determines how often a cache gets flushed.
The Load Security Server Policy Store Cache at Startup option loads this cache
every time you start ColdFusion services.
The Maximum Cache Entries option sets the maximum number of entries for each

Caching Advanced Security Information

Caching Advanced Security information can greatly improve performance within your
ColdFusion applications. The ColdFusion Administrator provides the following
Advanced security caches:
Security Server Policy Store Cache caches Advanced security information. You
can load this cache at startup. By default, it is notified of administrative changes
to the policy store once every minute. The information stored in this cache is
used to determine if a user is authorized for a resource. When this information
is cached, ColdFusion doesn't have to make database calls to determine this.
The result is that performance is greatly improved without requiring a lot of
information to be cached . Using this cache provides the most noticeable
performance improvements with Advanced security.
Security Server Authorization Cache caches each unique isAuthorized call.
Since each isAuthorized call is tied to the user who made the call, the number of
cached entries grows quickly in an application that has many users. Because
the high overhead of this cache can dampen its performance improvements,
you're better off using the Security Server Policy Store Cache if you anticipate
heavy usage of your protected applications.
ColdFusion Server Cache caches isAuthorized and isProtected requests. The
advantage of using this cache is it operates in the ColdFusion App server
process space so there is no interprocess call for cached request.
To learn how to configure Advanced security caches, see "Setting Up a Security Server"
on page 299.
