Session variables for anonymous users.

Hi
thanks for ur reply. I am not sure what u mean by hack or speed booster. But my problem is my module stores the search criteria in session variables. This is done for pagination. Like when i go to the second page i need to send the search criteria again to the server and this was done by session variables.

But when i come to the function that fetches result for 2nd page or others i can see that i lost all the session variables i previously created while i submitted the search form for the first time and i get only the latest session variables that i save for in this current request for second page. I tried by printing the $_SESSION and found all the previous session variables missing. And it happened only for anonymous users not logged in users.

For example:
my search keyword is 'test'. When i submit the search form, i saved this keyword in a session variable as, $_SESSION['search_text'] = 'test';
Now say i got results that requires 2 pages. Then when i click on the second page i go back to server for the result and found no session variable as $_SESSION['search_text']. as a result blank search returns default values for the rest of the pages.

Can anyone help why it happened for anonymous users???

Thanks in advance
