The maven project successfully added values to cookie in eclipse, but failed to add values to tomcat when deployed.

the project generates a number immediately after the user has successfully logged in. "token" is added to cookie as the key. Running in eclipse and using 360, Google browser can see this cookie value. However, when deployed to a remote tomcat server, you will not see the cookie value if you visit it again.
