44 Administering ColdFusion Server
Caching Settings
The Administrator Caching Settings page contains several configuration options you
can set or enable to cache templates, queries, and data sources.
Configuring Administrator Security
ColdFusion security options include two levels of security you can implement: Basic
and Advanced. With Basic Security, separate passwords secure access to the
ColdFusion Administrator, and to files, directories, and data sources from ColdFusion
Studio. Knowing these passwords gives you complete access to all resources and all
ColdFusion Administrator pages.
Advanced Security allows you to authenticate individual users and associate specific
access rights based on user login or group association. ColdFusion Advanced Security
gives you the ability to enforce security at a very granular level. For example, you can
define security domains and policies that allow you to secure specific areas of the
ColdFusion Administrator or specific ColdFusion resources, including the execution of
specific ColdFusion tags. This security framework allows you to authenticate
individual users, and, once authenticated, control access to a wide range of operations,
such as adding or deleting data sources, setting server performance options and so on.
For detailed information about configuring security options in the ColdFusion
Administrator, see the following chapters:
Caching Options
Option Description
Template cache
size Use this option to specify how much memory you want to reserve for
caching ColdFusion pages. For best performance, assuming your
server has enough memory, you should set this value to the total
number of kilobytes of all your active ColdFusion pages.
Trusted cache Allows ColdFusion to use cached application pages (templates)
without first checking to see if they’ve been changed.
Limit database
connection
inactive time Use this option to limit the amount of time ColdFusion allows a
cached dtabse connection to remain inactive. This option is ignored if
the option to maintain database connections has not been enabled
for an individual data source.
Limit maximum
number of
cached queries Limits the maximum number of cached queries that the server will
maintain. Cached queries allow for retrieval of result sets from
memory rather than through a database transaction. The maximum
number of cached queries allowed at any given time is 100. When this
value is reached, the oldest query is dropped from the cache and
replaced with the specified query.
