Application variables


There are some application variables that determine the behavior of an application. Inside the application, all the variables are stored inside this scope. The scope refers to the location where the .cfc file is found. Generally, this is not considered a good practice because the variables are not protected from outside the object. In Application.cfc, this is not an issue because there is no code to create an instance of the object for reuse. The following are the application-scoped variables in Appliation.cfc that you will use.

Variable

Default

Description

name

no name

This is the application name. If you do not set this variable, or set it to the empty string, your CFC applies to the unnamed application scope, which is the ColdFusion MX J2EE servlet context. For more information on unnamed scopes, see the Sharing data between ColdFusion pages and JSP pages or servlets section in the ColdFusion Developer's Guide (visit links at this book's website.)
