coldfusion Variables Setting a variable scope
Example
It is a common practice to set application variables to an object scope. This keeps them easy to identify and distinguish from variables in other scopes.
The Variables scope in a CFC is private to the CFC. When you set variables in this scope, they cannot be seen by pages that invoke the CFC.
<cfparam name="variables.firstName" default="Timmy">
<cfset variables.firstName="Justin">
Scopes shared with the calling page include: Form, URL, Request, CGI, Cookie, Client, Session, Application, Server, and Flash. Variables in these scopes are also available to all pages that are included by a CFC.
CFC:
<cfset url.sessionId="23b5ly17">
<cfinclude template="check_session.cfm">
check_session.cfm
<cfif url.sessionId eq "23b5ly17">
<p>Welcome back!</p>
</cfif>
