SSI in templates/forums??

[AnnieZC]

Hello all,

I have searched and couldn't find the answer to this (except for a very old post from 2001 on the vbulletin.com forum http://www.vbulletin.com/forum/showthread.php?t=30257 )

How do I use ssi in my forum?
Specifically, I use a simple banner rotation cgi script, and want to include the banners after the first post in every thread... I had this successfully working with another type of ad server, but can not get my simple ssi one to work.
I tried using <!--#include virtual="/cgi-bin/banlink.cgi" --> in the postbit template -- this code works on other parts of my site but not on by boards. Do I need something in the phpinclude template as described in the post I linked to?

Thanks.
