1. It can be used as a firewall to improve security.

Through the proxy server, users can set IP address filtering, restrict the access of the internal network to the external network, block the IP address, and prohibit users from accessing some networks, thus acting as a firewall.

2. Hide IP address and protect personal information.

The types of agents are roughly divided into three categories. Highly hidden agents, ordinary hidden agents, transparent agents. A highly hidden agent can hide the user's real IP address instead of the agent. A general hidden agent can hide the user's real IP, but it will change the request information so that the other party's server recognizes the dynamic IP agent we use. When a transparent proxy is used, the real IP address is transmitted, and the client has no idea that the proxy server exists.

3. Solve the network delay and improve the running speed.

It is a server, it has the function of storing memory. When external information passes or previously requested information is updated, it is automatically stored in the buffer. When the user accesses the same information again, the buffer can directly take out the information and transmit it to the user to improve the access speed.
