  2. 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 <CFAPPLICATION> tag • <cfapplication name=”someApp” value=”clientStorage”>

  7. 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 <CFINCLUDE> and <CFMODULE> • Specify a mapping with a “/” • <cfinclude template=”/test/query.cfm”>

  8. Debugging Settings • Typically, Debugging should only be used on a Development Server • Debugging can also be displayed without CF Admin intervention • <cfsetting showdebugoutput=”yes”>

  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
