Perhaps my post was missleading.

I am not intentionally trying to create cookies with the same name. I only need one cookie and it has a unique name, however when I inspect the value of $ENV{'HTTP_COOKIE'} using the perl code, I get more than one instance of the cookie, which may or may not have the same value. For example the value of $ENV{'HTTP_COOKIE'} might be something like: foo=bar1; foo=bar2

An example of the java code segment that I use to write the cookie:

var tkm = new Date(); tkm.setTime(tkm.getTime() + 96*3600000);
document.cookie = "foo=bar1; expires=" + tkm.toGMTString() + "; path=/
+";

Also note that I always access the cookie from the same location. Any clues?
