Hi,

i actual do my first steps with GWT.
Now I want to secure my web application. It is no problem, to build a
login dialog with username and password.
On several websites i have read, that I have to build a secure token
ant store it in a cookie to track the validility of the session.

For this, I have several questions:

1. What, if i can't use cookies. How can I remember, that the user is
still logged in?
2. If I refresh the page, the login dialog will be shown. How I can
display the last state of the website?
3. If I close the browser an open it again, and if I store the token
in a cookie, does the laste state of the session will be restored? I
hope not! If I close the browser, the session should not be reusable
4. I have read, that cookies can possible be a security problem. How
can I prevent this?

Can comebody help me?

Thank you
