IF URL Contains 'X' Code?

[howarde]

Is there a way to retrieve the URL in VB code similar to a php function that would be like:

PHP Code:

<?php if ($_SERVER['REQUEST_URI']=='/gallery/' ) {#Do What I Need Done;} ?>

Basically, I need to insert an ad zone, in the gallery, which in forums, I just use

vb:if condition="$GLOBALS[forumid]== foo"

But since /gallery isn't a forum and doesn't have a forum id... what should I use to find if the URL contains /gallery, any suggestions??
