Internet Explorer 8 Loses Cookies

"It is an IE8 bug. The IE8 process model is new and very flawed. If (when) IE8 processes hang or the computer is rebooted with IE8 open, cookies are lost.

To be very clear, it is not on ""some machines"" and not a 3rd party plugin or software issue. The problem has nothing to do with the cookie expiration date, the PC date or any other user or site controlled setting, it is a BUG in IE8, PERIOD.

Microsoft has yet to admit that there is an issue, so there is no fix for the issue. This and numerous other crippling BUGS in IE8 are being ignored, likely because they are too hard to fix and a result of serious flaws in the new process model that would require a ground up rebuild (IE9).

So... live with it or find another browser."

Switching to "/" as path for the cookie solved the problem for me. I had a more specific path before.

I just fixed my cookie disappearing problem. My problem was the date on this pc was set to tomorrow. IE8 deleted the cookies that were set to expire in a day or less. The best part is I picked up a whole day!
