I am using the mini web server that comes with jsdk2.0
sun.servlet.http.HttpServer class
(I am on Solaris 2.51 on a Sparc 1000 m/c)

Well, I do it like this
HttpSession ss = MyClass.getSession(req);
(so, I parse the cookies myself!! from the http header)
I have no choice about the cookies.
my domain is a.b.foo.com and so genius is setting cookies with a
domain of '.foo.com'
so I inherit ALL his cookies. Since he has a cookies with a value of
xx=somethingdsfsj
I get bitten by the getCookies() bug in JSDK
My workaround works, so i am happy. When Sun gets around to fixing
getCookies(), I will junk my classes
