This question doesn't really have a lot to do with Perl, but I am using Perl so I hope it's permissible to ask this here.
I am writing a Perl CGI program, which uses cookies, and I was just wondering what the correct way to format the expiration date is. When I use google and some books that I have, all of the answers are different. I gather that most browsers will accept several formats without complaint, but what is the official one?
