This article mainly introduces "what advantages should http agents have". In daily operation, I believe that many people have doubts about what advantages http agents should have. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what advantages should http agents have?" Next, please follow the editor to study!

1. High concealment. We don't have to worry about anti-climbing measures.

The reason why the crawler is blocked is that the anti-crawler mechanism detects the high-frequency access of the crawler IP, so only the high-hiding proxy IP can completely hide the real IP, so that we do not have to worry about anti-crawling measures.

2. The purity of IP supports batch use of API and high concurrency of multi-thread.

IP purity means that IP has fewer users and will not conflict with its own business. For example, exclusive IP pool, single use, the highest purity of IP; some open proxy IP platform purity is very low, can not use business conflicts. At present, Sun HTTP has provided services for many well-known Internet enterprises, which helps to improve the crawling efficiency of crawlers, support the batch use of API, and support multi-thread and high concurrency.

3. IP pool capacity.

The task of the crawler is generally large, and the anti-crawling strategy generally limits the number of requests per unit time of a single IP. If the capacity of the IP pool is too small, it is easy to work at a standstill, so the larger IP pool is more suitable for crawlers.

At this point, the study on "what advantages http agents should have" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
