Also, there's a good LGPL javascript library that has all the important
cookie functions (as well as a ton of other goodies) here:
http://cross-browser.com/

If you want to let the user auto-login (assuming it's not a site on which
security is critical), then a common thing to do is to store the username as
one cookie, and a HASH of username+password as another.  It's important not
to just store the password in plaintext, or a hash of the password alone
(because there are dictionaries of hashes of 8 or 9 characters available).

Best,
Daniel

You could use a cookie to store the username on the users computer.
It is saved by the browser actually so if the user logs in with IE and then
with
Mozilla, Mozilla won't know about the cookie set in IE.

Look at the servlet API:

javax.servlet.http.Cookie
javax.servlet.http.HttpServletRespone.addCookie(Cookie)
javax.servlet.http.HttpServletResponse.getCookies()



Thanks In Advance


Hope it helps
