When the session class loads at the start of a request, all session variables present in flash will be marked expired. In that request, their values will still be available.
When the request is finished, the cleanup will delete all session variables marked expired before the session data is written.
So unless you set a variable you get again or call keep_flash() for that variable, it will automatically be deleted at the end of the request.
This distinguishes flash variables from normal variables, which will exist until the session expires or you explicitly delete them.
Hi Harro, Not work for me. i have product tab and client tab, for example, and when i search "mo" (search method use flash for do pagination with this search on real time) into product, and change to client tab, clients are filtred with "mo" flash almacened.
