u can just put
HttpSession hs = req.getSession(true);
for the first page alone.
this command creates a session if it already does not exist.
if it already exists it uses the existing session.
Basically a session is maintained by either a cookie which is
stored in the client or by url rewriting.
so once the session is established
in the first page in subsequent pages u can just get
the value by using
hs.getValue("login");
//where hs is httpsession object
then based on the value(whether it is null or there is some value) u can
proceed accordingly.
