How to pass parameters if user clicks on the reload or refresh button on the browser

Hi

I am working on a web application that stores a value each time some user/client do some sort of search. And in the result page I display a look up number along with the result set. But if I click on the reload button the whole process starts again and it creates a new look up number and does all the search. I tried <t:saveState> to pass the value which works fine for the paging of the data table but doesn't work while I try to reload.

Can anyone please give me a hint or solution ..maybe an example code which would help me overcome this issue??

Regards
