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!

1. Solve the IP limitation: this is the most commonly used function for crawlers.

Because many websites now have anti-crawler technology, the common anti-crawler technology is to limit the number of IP visits. Therefore, when crawling, if the IP address used is blocked by the website, you need to use HTTP proxy IP at this time, and change the IP before you can continue the crawler work.

2. Improve work efficiency

When a crawler grabs information, if the crawler works slowly, the crawling speed will be limited. If HTPP agent IP is used, many kinds of crawlers can be used to crawl, which greatly improves the work efficiency.

3. Protect private information

High-quality HTTP agents are of great benefit to network security. Computers are protected from viruses, especially for enterprises, which can effectively protect internal information and prevent hackers from attacking.

4. Improve the download speed

For example, the download resources provided by some websites limit IP and threads. At this point, you can use the Sun HTTP Agent to break the download limit.
