1. Buffering can be added to improve access speed.

Usually, the proxy server will set up a large buffer, so that when the information of the website passes through, the corresponding information can be saved, and the next time you browse the same website or the same information, it can be called directly through the previous information, thus greatly improving the speed of access.

2. You can hide your real ip to prevent you from being maliciously attacked.

In fact, HTTP proxy also plays a very important role in crawlers. As we all know, in the process of crawling, we are likely to encounter situations where the current ip address is unusable or has ip restrictions. At this time, we tend to have a particular headache about ip. Of course, the proxy server allows the use of a large number of pseudo-ip addresses. On the one hand, it can meet the needs of the number of ip.
