本文发表在 rolia.net 枫下论坛There are textbook defintions on session. However, it is hard to recite the definition in an interview. My answer is try to argue away the interviewer and make him/her forget about the original question.
Session is not only a technical concept. It is
also a business concept. In the Internet world, as a surfer open the browser and
hits a URL, he/she begins a session with
the website. This session is composed of a series of request & response between the browser and the web server, until the surfer leave the site or he/she has idled for a too long time so that the web server expires
the session.
Techincally, session is incorporated in
a session object if your site is built using ASP. If your site is created using Java servlets and JSP, it is described by a HttpSession object. For a web developer,
he/she must keep session management
in mind. In another word, session management is the core of the Web programming.
My answer is not
really accurate, but I always use it to
confuse the people who interview me.
Talking some trivial things but make them sounds like truth is kind of a skill in a job interview. It does not always work but sometime it does work!更多精彩文章及讨论,请光临枫下论坛 rolia.net
