Is it possible to retrieve the creation or expiration date of an existing cookie from javascript? If so how?

If you are using Chrome you can goto the "Resources" tab and find the item "Cookies" in the left sidebar. From there select the domain you are checking the set cookie for and it will give you a list of cookies associated with that domain, along with their expiration date.
This code defines a function, setCookie(). This function will create a cookie with the name “username”, value “Max Brown” with an expiration date of 30 days from the time it was created.
Just set the expires parameter to a past date: document. cookie = "username=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/;"; You should define the cookie path to ensure that you delete the right cookie.
Cookies can expire. A cookie with no expiration date specified will expire when the browser is closed. These are often called session cookies because they are removed after the browser session ends (when the browser is closed). Cookies with an expiration date in the past will be removed from the browser.
It's impossible. document.cookie contains information in string like this:
key1=value1;key2=value2;... So there isn't any information about dates.
You can store these dates in separate cookie variable:
auth_user=Riateche;auth_expire=01/01/2012 But user can change this variable.
