Caching l.jpg
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


Caching3 l.jpg
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


Client variables l.jpg
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


Client variables5 l.jpg
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


Client variables6 l.jpg
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”>


Server side mappings l.jpg
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”>


Debugging settings l.jpg
Debugging Settings

  • Typically, Debugging should only be used on a Development Server

  • Debugging can also be displayed without CF Admin intervention

    • <cfsetting showdebugoutput=”yes”>


Debugging ip addresses l.jpg
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


Logging settings l.jpg
Logging Settings

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


Cfx tags l.jpg
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


Custom tag paths l.jpg
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)


Sandbox security l.jpg
Sandbox Security

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