Re: Login security question
If you do 1) you open yourself to XSRF attacks. Read this article (http://groups.google.com/group/Google-Web-Toolkit/web/security-for- gwt-applications) on how to avoid this by submitting a duplicate field with the cookie value and verifying it on the server end before executing the request For 2) the cookie is how tomcat figures out session to user relationship in the first place. I believe the cookie name is jsessionid for coorelating requests.
