You have the http.cache.setkey() which enables to make several caches.
We have a request to do something like:
<a target="_blank" href="http://community.riverbed.com/t5/Answers/Http-cache-and-setkey/td-p/26950">http://community.riverbed...
I have a site where client side tracking is made by URL paramters (for better and for worse)
Should all yield the same cached page.
It could be neat to have a function like http.cache.setkey() where you could calculate the pr url/request key.
