"out" can be used to output dynamic data to be mixed with static data in the JSP page to form the HTTP response.
"request" can be used to retrieve information from the incoming HTTP request from the Web browser.
"response" can be used to change behaviors of the HTTP response.
"session" can be used to share data between multiple requests to form a single process unit.
