This is more likely the cause (from Netscape again) <quote> The expires header lets the client know when it is safe to purge the mapping but the client is not required to do so. A client may also delete a cookie before it's expiration date arrives if the number of cookies exceeds its internal limits </quote> What you will have to do is encode your time in the value passed with the cookie and do your own checking...ignoring it if it is older than 10 seconds -- regards, Tom
