Thanks for your help! 

While I agree with you on making a move fully to
linux/apache/php, we have over 20 thousand products in our
database and these guys have many specific procedures they
have written for the sites as well. We are looking at using
httrack in a transition period on the way to linux/php. 

I had seen ETags mentioned previously, but no solid
documentaion on how to use them with httrack. I think this
is the option we will have to use to make this work. Could
you steer me to a good howto or give me some information on
who to proceed. Do I have to tell our IIS guy to turn them
on or anything or are they included in the html generated by
asp automaticly?
Again thanks for the help!
