However, the php coder can work around the annoying message from the browser by adding a little code into the script. The example shows a couple of lines of code that can be added above session_start() in order to be able to go back and forth to the page when you post without any hangups.The ‘private_no_expire’ mode means that the client will not receive the expired header in the first place.
header('Cache-Control: no cache'); //no cache session_cache_limiter('private_no_expire'); // works //session_cache_limiter('public'); // works too session_start();
