Cookies again: Expiry Date

[Andre Garzia]

Stephen,

I think you are using the wrong date format for the cookie. From wikipedia:

The expiration date tells the browser when to delete the cookie. The
expiration date is specified in the "Wdy, DD-Mon-YYYY HH:MM:SS GMT"
format. As an example, the following is a cookie sent by a Web server
(the value string has been changed):

Set-Cookie: RMID=732423sdfs73242; expires=Fri, 31-Dec-2010 23:59:59
GMT; path=/; domain=.example.net

That format is similar to the internet date but it is not the internet
date. I think you will need to assemble that out of the dateitems or
something. Other way is to encode your cookie value such as it carries
expiry information on the value field itself. For example

 Set-Cookie: one=valueone#1283719646;

Then on your code you split it using # as a itemdelimiter. valueone is
your actual value, the number after the hash is "the seconds", an
exact timestamp of when the cookie was set. You can use that on your
code to invalidate a cookie if needed. This puts the control of
expiration on your hands.
