Would this work with vBulletin?

This is a very interesting script that will cache a specified script, so I was wondering if this would work with some of the most used .php files of vbb, like search, showthread etc?

If it did I wonder if this would accelerate the viewing of a page!

why not just turn on vB's inbuilt gzip support ? my pages reduced in size from 68kb to 9kb using gzip setting of 1

I did turn it on, now how can I find out if it's working, and the size of my pages?
