Breaking access restrictions

Through the proxy server, you can break through its own IP access restrictions, access foreign websites, education networks, etc.

Increase access speed

Generally, the proxy server sets a large disk buffer and saves part of the response to the request in the buffer. When another user accesses the same information, the proxy server directly extracts the information from the buffer and sends it to the user to improve the access speed.

Hide the real IP address of the client

Internet surfers can also hide their IP addresses from attack in this way.

The reverse proxy

Hide the real SERVER IP address

Using a reverse proxy, you can hide the IP address of the server from the client.

Load balancing

The reverse proxy server can perform load balancing and distribute client requests to different real servers based on the load of all real servers.

routing

Increase access speed

The reverse proxy server can cache static content and dynamic content that has a large number of access requests in a short time to improve access speed.

Provide security

The reverse proxy server functions as an application-layer firewall to protect Web sites from web-based attacks, such as DoS and DDoS, making it easier to check malicious software. It also provides encryption and SSL acceleration (such as SSL terminal proxy) and HTTP access authentication for back-end servers.

The difference between

Although the forward proxy server and reverse proxy server are located between the client and the real server, and do what the client requests to the server, the server response to the client, but there are some differences between the two.

  1. A forward proxy is actually a proxy for the client, helping the client access server resources that it cannot access. Reverse proxy is the proxy of the server, helping the server to perform load balancing and security protection.

  2. Forward proxies are usually installed by the client, such as installing a proxy software on its own machine. A reverse proxy is usually deployed on a server. For example, a reverse proxy server is deployed on a cluster of hosts.

  3. In forward proxy, the server does not know who the real client is and thinks that the real client is accessing it. In a reverse proxy, the client does not know who the real server is and thinks it is the real server it is accessing.

  4. Forward and reverse proxies have different roles and purposes. Forward proxies are mainly used to solve access restriction problems. Reverse proxy provides load balancing and security protection. Both can improve access speed.
