This article mainly explains "what is the role of HTTP agent", the content of the explanation is simple and clear, easy to learn and understand, now please follow the editor's train of thought slowly in depth, together to study and learn "what is the role of HTTP agent"!

1. Convenient for users to manage.

Set up the user confirmation and accounting function, which can be recorded according to the user. Unregistered users do not have access to the Internet through a proxy server. Calculate the time, location, and information flow of user access.

Users are graded, different user access restrictions are set, external or internal Internet addresses are filtered, and different access restrictions are set.

2. A large hard disk buffer will be set to improve the access speed.

In general, the proxy server sets up a large hard disk buffer (up to several GB). If the external information is passed, it is also saved in the buffer. If another user accesses the same information again, it extracts the information directly from the buffer and transmits it to the user, speeding up the access.

3. Improve the speed of web browsing.

The agent Server receives the data provided by the remote server and stores it on its own hard disk. Many users use proxy servers at the same time, and all their requirements for Internet sites are realized through proxy servers.

If someone visits a site, the information on the visited site is saved on the hard drive of the proxy server. The next time you visit the site, this information will be obtained directly from the proxy service without the need to connect to the remote server again. This can save bandwidth and improve access speed.

4. It can be used as a firewall.

Proxy Server can protect the security of LAN and play the role of firewall: for LAN where proxy Server is applied, proxy Server can only be seen externally, while proxy Server can not be seen by other users. Proxy Server acts as a barrier to LAN security.

In addition, users can also set IP address filtering through the proxy server to restrict external access to the internal network. Similarly, proxy servers can be used to restrict the blockade of IP addresses and prevent users from accessing certain web pages.

5. Save IP cost and online resources.

Proxy Server allows the application of a large number of pseudo IP addresses, saving online resources, and even using proxy Server can reduce the need for IP addresses. If the local area network is used to access the Internet, each user only needs to apply for an IP address for the local area network, and the cost can be imagined.

However, after using the proxy server, as long as there is a legitimate IP address on the proxy server, other users in LAN can use such a private IP address, thus saving a lot of IP and reducing the cost of network maintenance.

Thank you for your reading, the above is the content of "what is the role of HTTP agent". After the study of this article, I believe you have a deeper understanding of the role of HTTP agent, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
