Remvoing external.php on external pages

[mooreaa]

Hello,

I have my site setup as such:

mysite.com/forums/ vbinstall
mysite.com/tos.php

tos.php is an external page that uses the template system and everything is working just fine except I want to disable the RSS feed on my tos page

I see the condition its looking for in headerinclude: $vboptions['externalrss']
But when I set this variable from my tos.php script : $vboptions['externalrss'] = false;

it doesn't do anything.

How can I turn this off from some of my pages?
