strip query terms OnOff

[srnoam]

Hello,
I am implementing am trying to implement caching of dynamic objects in my
network enviroment, I have used "strip query terms Off" & got to "see" the
whole "object" in the logs, however I couldn't get it to "swapout" & stay in
the cache, I only got it to "swapout" & then "released".
It seems there is a problem with the "?" in the object name.
I use 2.5 stable 7, is there a way to fix that? 
thanks,
Noam
