Active User objects and the membership Directory
The problem that we often encounter in the programming technology of the website is how to track the user's information, especially
is when the number of users as high as millions of, can be very convenient to manage users and also requires
Server's high performance. The following is an introduction to using AUO (Active User Objects) technology to implement this functionality.
Introduction to some basic
Use AUO (Active user Object) to maintain user information
If you don't understand some of these technical terms,
Please refer to the article I sent earlier about ADSI.
Now when the Web site programming, to save the user information is often used
Technology is:
1. Using the Session object to save user information is a common way to allow
You add a session variable to any location in your program, and it's not

can have many Web servers driven from a Dynamic Data server and a replica of a Dynamic data server used in fault tolerance. Perhaps this wonderful dynamic Data server can be executed on the site server with an Membership Server and an ActiveX User Object (AUO). An introduction to AUO can refer to Active User Objects the Membership Directory.

load-balanced router to allocate requests from the client to one of the Web servers. However, once a user starts an ASP session with a Web server, all subsequent requests are returned to the Web server, which means that if the server is shut down, the user loses their session and the performance problem arises if the server is overloaded. There is a workaround: Do not use the Session object.
There are other ways to maintain user status. You can store them on the client with an implied structu

In the past two days, we have selected a 4.3-inch LCD screen for the fs_s5pc100 development platform of our R D center. Finally, the a043fw02 V0 of Auo is set in many screens. I thought that the units that sold the screen could provide reference backlight images, but most of the results were not. A customized backlight can be provided, but it is expensive. Select your own power supply.
