How a reverse proxy server works

  The reverse proxy method refers to the proxy server to accept the connection request on the Internet, and then forward the request to the server on the internal network; and return the result from the server to the client requesting the connection on the Internet, at this time the proxy server It acts as a server externally. So how does it work?

How a reverse proxy server works

  You can use multiple proxy servers in an organization to balance the network load among web servers. In this model, the cache feature of the proxy server can be used to create a server pool for load balancing. At this time, the proxy server can be located on either side of the firewall. If the Web server receives a large number of requests every day, you can use a proxy server to share the load of the Web server and improve the efficiency of network access.

  For the client’s request to the real server, the proxy server acts as an intermediary. The proxy server will store the requested document in the cache. If there is more than one proxy server, DNS can use “round-robin usage” to select its IP address and randomly route the request. The client uses the same URL each time, but the route taken by the request may go through a different proxy server each time.

  Multiple proxy servers can be used to process requests to a high-volume content server. The advantage of this is that the content server can handle a higher load and is more efficient than when it works alone. During the initial startup, the proxy server retrieves documents from the content server for the first time, after which the number of requests to the content server will drop significantly.
