Are cookies Year 2000 Compliant?
There is no date-specific restriction on the HTTP header used to transmit cookies. In fact, the only determining factor in whether a cookie will be accepted is the programming of the client receiving the cookie. The major browsers do not have an issue with this. Cookies with expiration dates set with 2-digit or 4-digit years are understood properly. Naturally, it’s always advisable to use 4-digit years when setting cookies.
