How check the requested URL in ColdFusion

Question

I've written the code below in the onRequestStart method of my Application.cfc. So whenever a request comes before the session value creation it will always redirect to login_action.cfm.

<cfif not IsDefined("session.active")>
   <cfinclude template="login_action.cfm">
</cfif>

In the login_action.cfm is code for blocking the access of other pages without a proper authentication:

<cfif NOT (IsDefined ("Form.username") AND IsDefined ("Form.password"))>
     <cfinclude template="login.cfm">
     <cfabort>
<cfelse>

Now I created a signup page. This page doesn't need an authentication. Everyone should able to go that page by a single click, but now it is not possible without login. Can I change this by checking the targtedPage argument of onRequestStart method somehow?

Can someone help me?

Can I check with this by the targtedPage (sic) argument of onRequestStart method?

Answer

Yes.

Using your existing code structure and making a presumption of calling your signup page signup_page.cfm you can do the following.

<cffunction 
    name="OnRequestStart" 
    access="public" 
    returntype="boolean" 
    output="false" 
    hint="Fires at first part of page processing.">

    <!--- Define arguments. --->
    <cfargument 
        name="TargetPage" 
        type="string" 
        required="true" />


    <cfif FindNoCase( "signup_page.cfm", arguments.TargetPage)>
        <!--- User is at the signup page, no need to check for an active session. Do stuff if necessary here. --->
    <cfelse>

        <cfif not IsDefined("session.active")>
            <!--- User's session is inactive, redirect --->
            <cfinclude template="login_action.cfm">
            <cfreturn false />  <!--- You should add this return in your existing code. --->
        </cfif>

        <!--- User is logged in with an active session, do other stuff. --->

    </cfif>

    <!--- Return out. --->
    <cfreturn true />

</cffunction>
