Are you using any php script while generating the search page? I mean if your search page is a .php file then IE normally expire the session for the page. If its a normal HTML page then you shouldn't have this problem.

hi,

I have a search page with some checkboxes & dropdown lists.

& used only php coding with html.
But when i came back by clicking browser's back button from search results page to search page :

1) IE shows "web page expired" message & again cliking on back button then display search page with previously selected checkboxes r unchecked.

2) In firefox automatically come back on search page. but selected checkboxes shows unchecked.

Pls. send javascript code or any php code for handaling browser problem & select problem.

Thanks,

Two solutions:
a) hit your refresh button.
b) code the search to use $_GET rather than $_POST

Another option is to emit headers from PHP which allows IE etc to cache the search results page for a little while

e.g.

header('Pragma: ' . 'public');
header("Cache-Control: public");
header('Expires: ' . gmdate('D, d M Y H:i:s', time()+(60*10)) . ' GMT'

I had the "page expired" problem and this allows me to back button back to the PHP search results page.

Performing another search gives you fresh results to this doesn't clog up your cache or anything.
