Page expired after returning to search form

Hi Everybody,
Some customers complained to us that they have the error "Page has expired" when they click on Back button (of browser) to go back to Search result page (of advanced search) from property details page. And they must re-load the page to see the search result again.
To solve this issue, please try to use this plugin plg_expiresheaders.zip
Thanks
