Cookies anyone?

While rummaging around in my cookie jar, I found this message--along with some cookies. :Netscape HTTP Cookie File :# http://www.netscape.com/newsref/std/cookie_spec.html :# This is a generated file! Do not edit. Rather than bring down my system by experimenting, I thought I'd ask the list, "What happens if I delete this file?" and "What happens if I delete (edit) the cookies?" This may have been discussed before, but until now I never checked for cookies. Thanks for your consideration of this matter. Vanished
