Page Warning Error

[ajidnair]

Dear All,

I have a search page configured to display 20 results per page using PHP 4 and MySql 4.1. My problem is that whenever after a search {POST}, i hit the back button i get a "Page : Expired Warning". I Want to get rid of this problem. When i use the following code, i m able to overcome this problem.

header("Cache-Control: private");
ini_set('session.cache_limiter','private');

But then, my search results are cached and my search results are thrown from the cached pages. I would want a suggestion for eliminating this warning and the caching !!


Please help ::: Thanks in Advance !!
