Then create the ASPStat DatabaseThen we configure in web. config: After the configuration, we can see the session information in the session database.Next, let's test. First, I access the site on IIS in the 360 browser: In the session database:Firefox browser testing: In the session DatabaseThe multi-site session sharing is indeed implemented, but this design performance is not good in the actual project. We recommend that you use redis and memc

insufficient, the scalability is not enough, the problem of low reliability. The expansion of the system can be divided into vertical (vertical) and horizontal (horizontal) extensions. Vertical expansion, from the point of view of a single machine to increase the hardware processing capacity, such as CPU processing capacity, memory capacity, disk and so on, to achieve the improvement of server processing capacity, can not meet the large-scale Distributed System (website), large traffic, high c

upper limit, and there is basically no consumption in memory and CPU. 2. Low configuration, which is usually a major disadvantage, but it is also a major advantage. because there are not many configurable options, you do not need to touch the server frequently except increase or decrease the server, this greatly reduces the likelihood of human error. 3. Work is stable. Because of its strong load resistance capability, high stability is also a logic.

Nginx implements load balancing and nginx Load Balancing Load Balancing with nginx The functions and advantages of Nginx do not need to be mentioned here. Today, we mainly use the nginx Server

In windows, ARR of IIS is used to achieve site load balancing and arr load balancing.1) Purpose: Access localhost: 18066 Load the following two ports Localhost: 18098 Localhost: 18099 2) means: 1. Use nginx 2. Use the ARR (Application Request Routing) of iis) 3) use the ARR
