I'm looking for a way to set cookies with a short duration against all browsers. Apparently each browser handles the PHP setcookie method differently. Below are my results.
The PHP code:
setcookie("TestCookie", $value, time()+7200, "/", ".domain.com", 1, true);
The Results:
OPERA 11.10
Local time of test: 1316621628

As you can see, the expiration date/time for the cookies varies widely from working as intended to being several hours in the past to only being 1 hour! Very frustrating.
In addition to trying the above method, I've also tried setting the exact expiration date/time via unixtime... I've done this with both time() at the PHP level, or utilizing the browser's unixtime retrieved through JavaScript.
setcookie("TestCookie", $value, 1316621928, "/", ".domain.com", 1, true);
Each browser handles this differently as well. I can't seem to find one method that works the same for all browsers. Is anyone aware of a method that accomplishes this?
Thank you.
