This article introduces the relevant knowledge of "what are the advantages of online agent ip". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The principle of online proxy is that when receiving the browsing requirements of browsers (such as ie, etc.) for remote websites (when the browser client submits the website), the agent begins to look for the remote website on the current server. As soon as the target site is found, the agent immediately returns the site data to the user's browser client. If the current server does not have a cache from the remote server, the agent automatically reads the remote site and submits the information from the remote site to the client, while providing the information cache to the next browsing requirement. The agent automatically deletes the cache based on the cache time, size, and extraction record.

Online agents have many advantages:

1. Connect the Internet and the Internet as a firewall (firewall).

Because all internal network users access the outside through a proxy server and are mapped into only one IP address, the external network cannot directly access the internal network; at the same time, IP address filtering can be set to restrict external access to the internal network; in addition, two internal networks that are not interconnected can also exchange information through a third-party proxy server.

2. Save IP costs. As mentioned earlier, all users only occupy one IP and do not need to rent too many IP addresses, thus reducing the cost of network maintenance.

In this way, many machines that are not connected to the external network can connect to the external network through the proxy server of the internal network, which greatly reduces the cost. Of course, it also has its disadvantages. For example, many network hackers hide their real IP addresses in this way to escape surveillance.

3. Improve the access speed, reduce the bandwidth, and connect with the target host through the proxy with large bandwidth.

And usually the proxy server sets a large hard disk buffer (which may be as high as several GB or more). When external information passes through, it is also saved in the buffer. When another user accesses the same information again, it will directly take the information out of the buffer and transmit it to the user, thus improving the access speed.
