This article mainly explains "what are the functions of the proxy server", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the functions of the proxy server"?

1. Shared network.

For example, access to information from external websites through proxy servers such as Squid,sygate,wingate,isa,ccproxy and NT systems that come with network sharing. At the same time, these proxy servers can also provide enterprise-level file caching, replication, address access and other services. Making full use of the limited bandwidth of LAN exit and speeding up the access speed of internal network users can solve the problem of public IP. If public IP resources are seriously short of public IP resources, it can meet the needs of many users of LAN to share the Internet at the same time.

2. Access the agent.

In today's network environment, there are often network congestion or network failures. Users usually make a detour to the target site through the proxy server; in addition, the proxy server usually backs up a considerable number of cache files. If the currently accessed data is in the cache file of the proxy server, it can be read directly without connecting to the remote network server. This can increase the speed of website access and save communication bandwidth.

3. Improve the speed.

Improve the download speed, break through the restrictions of IP, download threads, and telecom and Unicom users download movie websites to each other.

4. Break through the limit.

There are many open proxy servers on the Internet. When customer access is restricted, access to these proxy servers is unrestricted. The proxy server happens to be within the scope of the customer's access, and the customer can access the target website through the proxy server. Using the proxy server, domestic universities can access the Internet through the education network, which is why the proxy server of the university flows.

5. Prevent attacks.

Access to the internal host through the proxy server, host address and other information will not be sent to the outside, you can hide your real address information and IP. More effective protection of internal hosts.

6. Used as a firewall.

Because all users using the proxy server must access the remote site through the proxy server, they can set appropriate restrictions on the proxy server to filter or block some information.

7. Convenient for users to manage.

Through the proxy server, the administrator can set up user authentication and accounting functions, register users, and count the access time, place and information of users. Unregistered users do not have access to the Internet through a proxy server.

8. Hide your identity.

The proxy server is protected when using internal users to access the Internet, and internal network users need to use the reverse proxy function of the proxy server to publish external information. This will not affect the security performance of the internal network and play a role of hiding identity.

At this point, I believe you have a deeper understanding of "what are the functions of the proxy server?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
