In the process of writing a desktop software, use the WebBrowser to implement the interface. There is a requirement to prohibit WebBrowser from being refreshed via the F5 button. In the spirit of doing while learning principle, this dish checked Baidu, originally so simple, code as follows: This false;Haha, success. Continue to complete the next task, write and write, found the wrong, very wrong. Just that code, not only the
F5 forwarding Mode1. Transparent mode: Performance L4This type of virtual server. F5 processes packets in a pure four-tier manner, looking only at source IP, source port, destination IP, and destination port.

Based on the huge network structure, the use of cluster servers brings a lot of traffic and other load problems. In contrast, Server Load balancer technology has also emerged. Every technology requires Product Support. Now let's get to know one of F5 Server Load balancer. First, we will introduce the structure and functions of the product.
Many vendors have launched load balancers dedicated to balancing server loads, such as
Disable ctrl + n and ctrl + r for the JS Code that disables F5 and other shortcut keys, and disable shift + f10 for the right-click or right-click for the JavaScript code that disables f5.

Load balancers are often referred to as four-tier switches or seven-tier switches. The four-layer switch mainly analyzes the IP layer and the TCP/UDP layer to achieve four-layer flow load balancing. In addition to supporting four-tier load balancing, the seven-tier switch also contains information on the analysis application layer, such as HTTP protocol URI or cookie information.
