Application, server, and Session objects

(a) application Object        

Application object is Web on an application-level object, which can be a set of ASP files, these ASP files work together to accomplish a task. The user stores and accesses variables from any page.

Application objects contain data that can be used by all users of the application and can be persisted during the site run. This information can be changed in one place, and these changes are automatically reflected on all pages.

Application event for the object:

(ii) Session

Sessionrepresents a "session" between the server and the client, and the action time from the user to a specificWebpage begins, to which the user leavesWebsite, or use code in your program to terminate aSessionend. SessionThe relationship with the user is one by one corresponding, the system for each visitor has set up a separateSessionobject that is used to storeSessionvariable, and the individual visitor'sSessionobjects do not interfere with each other .

           talked aboutSessionI have to talk about it.Cookies, because they are closely related. Sessionuse requires that the user's browser must supportCookiesIf the browser does not support the use ofCookies, or set to disableCookies, then you will not be able to useSession.

I used to learn about the news release system Cookies with the Session also a detailed summary of the specific details please see: http://blog.csdn.net/xdd19910505/article/details/39140163
