使用IE时Cookie删除问题

Question

Okay, my site is written in PHP. I'm having problems with IE sometimes not deleting the cookies. Here's my log out code.

setcookie("user", "", time() - 50000000);

setcookie("pass", "", time() - 50000000);

header("Location: index.php");

This works great in Firefox, Chrome, etc. But IE sometimes won't delete the cookies?

My login when setting cookies looks like this:

setcookie("user", $result['Handle'], time() + 50000000);

setcookie("pass", $pass, time() + 50000000);

header("Location: news.php");

I just don't understand why it will clear it most of the time, but gets stuck other times.

Answer 1

Be careful you are not setting cookie at different directory levels. This will effectively create two cookies for the same domain but with one set for a sub-directory/path. I.e. www.example.com vs. www.example.com/mypath. It is possible you set the cookie for a sub-path in addition to the root and are now deleting only the cookie for the sub-directory so the root cookie remains. I don't believe this would be an IE specific behavior though.
