I set a cookie with Perl.  Now on each page, I'm going to include a piece of javascript that checks if the cookie exists.  I don't care what information the cookie holds because it doesn't matter.  I just want to know if the cookie exists.  If it doesn't exist, I'm going to redirect to an 'Error' page.  Any ideas?

when I say 'each page', I mean that I'm going to include a piece of javascript on each HTML page.

if (!document.cookie)

}

How does that code know which cookie I'm looking for?

Sorry brain fart:

var offset=-1;
if (document.cookie.length > 0) {
offset = document.cookie.indexOf("yourname=");}
if (offset == -1) { //re-direction code}
