Reviewing the code
The Application.cfc page executes before the code in each ColdFusion page in an application. For more information
on the Application.cfc page and when it is executed, see
page 235.
The following table describes the CFML code in Application.cfc and its function:
Code
<cfcomponent>
<cfset This.name = "Orders">
<cfset This.Sessionmanagement="True">
<cfset This.loginstorage="session">
<cffunction name="OnRequestStart">
<cfargument name = "request" required="true"/>
<cfif IsDefined("Form.logout")>
<cflogout>
</cfif>
<cflogin>
<cfif NOT IsDefined("cflogin")>
<cfinclude template="loginform.cfm">
<cfabort>
