Yes, containing only the id of the HttpSession living on the server. You
can look at this cookie's contents by watching the HTTP traffic between
client and server using LiveHTTPHeaders (a Firefox add-on) or similar
add-on to another browser, or by using a TCP sniffer such as Wireshark.

I suspect that you had another browser window opened somewhere. If you
don't close all the browser windows, then the browser is still
considered to be running, and your cookie will continue to be sent.

This was an incorrect statement.

Cookies can have only one value. The JSESSIONID cookie has the only
value it will ever need: the id of the session. Don't mess around with
the JSESSIONID cookie.

I think you need to be more clear about your requirements. Do you just
want to know if the user has visited your "second servlet" during their
session? If so, then you can simply store that fact as an attribute of
the session. Something like this:
session.setAttribute("did-visit-second-servlet", Boolean.TRUE);
You can check for this value like this:
if(Boolean.TRUE.equals(session.getAttribute("did-visit-second-servlet")))
{
response.sendRedirect("http://www.google.com/";);
return;
}
