Cache problem

Hi,
Actually I really don't know, it's cache problem or something else
I made a searching page that contains info page number, current page and 
other things.

The problem exists when 2 users got connected to server and opening the 
same page, example "SearchPage".
If #1 user enter key for search and jump to next page of search result, 
when the #2 user goes to "SearchPage" he will have same page and same 
"search key" just like #1

1. Is it because that both user using same page number and same key that 
stored in cache?
2. How to avoid this? disabling-cache can't help much. because i must 
store currentpage and pagenumber variable.


Thanks for Help
If there is already discussed topic about this, would you mind to give 
me url address,

Regards

Edy Toha
