>with the access time
Http is stateless and "access time" is meaningless. You could start the day by opening, say, an IE window to Google, then proceed to open other apps and work. At the end of the day, you log off and Windows terminates IE. Have you been Google-ing all day? In general, the Web server wants to push output to you and be done with it. Your Web client displays that output, but it doesn't know what you're doing.
