Thanks for the reply Buro9. I wonder if it's possible to get a step-by-step guide how to remove all the sessionhashes on every page where it is needed. If you or anyone has that amount of spare time of course
filburt1's beta script looks like something that could work with AdSense too, this might be interesting to look into. Did anyone try anything like this out for AdSense?
EDIT: VB3 works like a charm with AdSense. I can't wait for RC1 (just like nearly everyone else here).
