Deleting Cookies
The method for deleting cookies is not intuitive. To delete an existing cookie, you must set its expiration date to a date in the past.
The page in Listing 28.5 illustrates how you can delete a single cookie. The page contains a form field for the cookie name. When you submit the form, the cookie with the specified name is deleted.
Listing 28.5. DeleteCookie.aspx
The particular date that you specify when deleting a cookie doesn’t matter as long as it is in the past. In Listing 28.5, the expiration date is set to one day ago.
