SV: page refresh cleans my page state
Hi
I have gone through the HybridUrlCodingStrategy. The HybridUrlCodingStrategy is
working porperly in WebApplication but not in portal environment. In
WebApplication it retain the page state but not in portal environment.
Please suggest what should I do in portal environment.
Thanks in advance.

It is ok but if I click on browsers refresh button all changes are
