Hi, This has to do with cookies, but I thought someone here could help. I have a perl script that has people submit user/pass into a sql database, and then sets a cookie as follows: 
sub write_cookies { 

    print "Set-Cookie: reguser=$username; expires=$expires; path=/;\n"
+;
    print "Set-Cookie: regpass=$password; expires=$expires; path=/;\n"
+;
    print "Set-Cookie: regtype=$regtype; expires=$expires; path=/;\n";
}

So it prints a username, password, and regtype (regtype tells whether they're a member or not). So then I have the following code on pages that I only want members to see: 
<script language=javascript>
{

    var the_cookie = document.cookie;
    var the_cookie = unescape(the_cookie);
    var broken_cookie = the_cookie.split("=");
    var the_regtype = broken_cookie[3];
    if (the_regtype != 'member') {
        window.location="http://www.domain.com/cgi-bin/login.pl?logout
+=yes";
    }

}
</script>

This works if I only use this script. The scripts checks the database and only let's people in that are registered, and presents a login screen to others. My problem is that I'm also running an online photo album software that sets a 4th entry into my cookie. In IE, my code still works but in Firefox I can only get it to work by changing the 3 to a 4 in this line in the javascript: 
var the_regtype = broken_cookie[3];

changes to: 
var the_regtype = broken_cookie[4];

If I change the 3 to a 4, it works in Firefox but not in IE. Is there a way around this? Is this a Firefox bug? If I delete the photo script's cookie my script works fine. Any insight would be appreciated.

On another note. How secure is this type of security? If people can login once, view the source of my HTML and get the javascript code, could they conceivably build their own cookie to get around my script? Thanks. Tom
