JSP Data interaction

Cookie vs. Session scope
1, session scope is to save the user information on the server side, the cookie is to save the user information on the client.

2. The value stored in the session scope is the object type, and the value stored by the cookie is of type string.

3. Session scope destroys the data stored by the session, and the cookie can be stored on the client for a long time.

4. Cookies usually save unimportant user information, and important information is saved using session scope.
