Many users have heard of dynamic forwarding proxy IP, but don't know what dynamic forwarding is, and don't know what advantages it has. Today Tianqi will discuss it with everyone.
We know that the normal process of sending a request using a proxy IP (also called a proxy server) is as follows: the client sends a request to the proxy server, and the proxy server forwards the request to the target website server; the target website server returns information to the proxy server, and the proxy server will The information is forwarded to the client. After this process is completed, the client will switch to another proxy IP, and then continue to start the same work, and then switch the proxy IP, repeating...
The workflow of dynamic forwarding is as follows: set a server (tunnel) as a proxy server, the tunnel server will automatically assign a proxy IP, the client sends the request process as above, first send the request to the proxy server, and the proxy server forwards To the target website server; the target website server returns information to the proxy server, and the proxy server forwards the information to the client. After this process is completed, the tunnel server will automatically switch to another proxy IP, and then continue the same work, and then automatically switch the proxy IP...
Through the comparison of the above two, we can see that dynamic forwarding has an additional function of automatically switching the proxy IP, which does not require the user to switch the proxy IP. After the user sends a request, it will automatically switch the IP, and the user does not need to care about the proxy IP. How long does it take to fail, and when should I switch the proxy IP?
