Caching

• Template Cache Size
• Set to number of templates
• Too low of a number can make pages slow to load
  since not all will be cached
• Too high of a number, more memory is allocated
  than necessary
• Trusted Cache
• When checked, Coldfusion no longer looks for
  updated templates for thos that are cached
• Great for a production server that won't be
  updated

3
Caching

• Limit Cached Queries (default 100)
• Allows you to specify how many queries can be
  cached at once
• Cached queries reside in memory
• When limit is reached, oldest cached query is
  kicked out

4
Client Variables

• Client variables are used for persistent data
• Can be stored in one of 3 locations
• Registry (default)
• Cookies
• Datasource
• The registry can become corrupt if it becomes too
  large
• Users can have cookies disabled
• A datasource requires a database

5
Client Variables

• You can control how long client variables last
• Default is 90 days
• Minimum is 1 day
• The longer the period of time, the larger the
  client storage becomes
• Disable Global Client Variable Updates
• If checked, a client variables HITCOUNT and
  LASTVISIT are only upaded when client variables
  are set or modified

6
Client Variables

• Disable Global Client Variable Updates (cont)
• Client variables expire based on the HITCOUNT and
  LASTVISIT
• Although the default storage for client variables
  is set in the CF Administrator, an alternate
  storage can be specified in the ltCFAPPLICATIONgt
  tag

Server Side Mappings

• Mappings allow you to point to files that are
  outside of your webroot.
• Logical Path The Name of the Mapping
• Directory Path Absolute Path to Directory
• Mappings can be used in ltCFINCLUDEgt and
  ltCFMODULEgt
• Specify a mapping with a /
• ltcfinclude template/test/query.cfmgt

Debugging Settings

• Typically, Debugging should only be used on a
  Development Server
• Debugging can also be displayed without CF Admin
  intervention
• ltcfsetting showdebugoutputyesgt

9
Debugging IP Addresses

• When no ip addresses are specified and debugging
  is turned on, debug info is appended to all
  requests
• By specifying IP addresses, debug information is
  limited to those IP addresses

10
Logging Settings

• Logging settings can come in handy on a
  productionn server to help monitor the
  performance and any potential bottlenecks within
  the application

11
CFX Tags

• CFX Tags have to registered with the ColdFusion
  Administrator
• They are written in C or JAVA
• Run faster than Custom Tags written in Coldfusion
  since they are compiled
• Tags written in C are .dll files on Windows and
  shared objects on Unix

12
Custom Tag Paths

• The default custom tag path is in the
  installation directory for ColdFusion
• Additional Custom Tag Directories can be
  specified for Custom Tags that reside else where,
  (i.e. A seperate partition)

13
Sandbox Security

• Sandbox Security allows for you to set special
  restrictions for specified applications
