Hello. 
I mirror a large dinamic site witch containts random generated banner so the
size of each page changes depending of the name of the banner. 
There are 2 types of urls for the pages from the site pages:
www.aaa.com/show.php?id=xyz
www.aaa.com/show1.php?id=xyz
I would like to update only the first type of pages because in the second type
the only thing that changer is the banner.
Is there any way to do that?
