Accessing file inside the application from an emai llink

I am adding a new functionality to an old coldfusion application. The new fucntionality is to send email to users of the application. Fo that I have to generate an email which has a link to one file inside the application which does updation in datbase. The problem is that whenever user clicks on that link the 'main' page appears, ie index.cfm. what could be the problem?Does it has anything to do with the settings inside 'application.cfm'
Example email link will be like this:
**********************************************
<CFMAIL TO="#tomail#" FROM="#from_mail#" SUBJECT="test">

Please click on the following link to review and take action

http://myvirtualdir/myapp/app1/approve_Page.cfm?User=test_user
</CFMIL>

**********************************************
The above link should open the file named approve_page.cfm
But now, when I click the link it goes directly to the index.cfm page


thanks in advance

I'd look for code in the Application.cfm file that is forcing all calls to the application to go to index.cfm. By default it shouldn't matter and CF would render the page in the link, so something else is stopping it.
