how to use login name in other pages?(without cookies)

[Caven Wang]

How can the login information in other pages? for example, the visitor inputs his username and password in the index.html. The name and password are checked in the login.jsp. If passed the checking, it will be directed to a welcome.jsp. What should I do now?

well, without using cookies explictly (it does use cookies but not by us) you can set attributes to the session object and check it in the other jsp or servlet.
for example:

session.setAttribute("username",username);

assuming username is a String.
in the other servlet or jsp you can retrieve this attribute and check if it is equal to the username.
thats it.
