Proxy server is an important tool in the network, which can provide users with safe and anonymous network access. This article explains how proxy servers work, the different types, and their common uses on the web.

1. Working principle of proxy server

A proxy server acts as an intermediary between the user and the target server, receiving requests from the user and forwarding the request to the target server. The target server sends the response back to the proxy server, which forwards the response to the user. This middleman role enables the proxy server to filter, cache, and modify incoming requests, providing additional security and performance benefits.

2. Types of proxy servers

①Forward proxy

The forward proxy is located between the client and the target server and makes requests to the target server on behalf of the client. It can help clients bypass network restrictions, protect user privacy, and increase access speed.

②Reverse proxy

The reverse proxy sits between the target server and the client and sends responses to the client on behalf of the target server. It can help with load balancing, caching static content, and protecting target servers from malicious attacks.

3. Purpose of proxy server

① Improve network performance

Proxy servers can cache static content, reduce the load on the target server, and increase user access speed.

②Protect privacy and security

Proxy servers protect users' real IP addresses and protect them from online tracking and surveillance.

In conclusion

Proxy servers play an important role in the network, providing users with secure and anonymous network access, while also bringing the convenience of performance optimization. Therefore, both individual users and corporate organizations can benefit greatly from using a proxy server. Lunaproxy has the characteristics of stable server and high security.
