What are the reasons why web crawlers use proxies?
This article will explain in detail the reasons for web crawlers to use agents. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
The proxy server is located between your web crawling tool and the website it is crawling. Your HTTP request for any website will first pass through the proxy server, and then the proxy server will pass its request to the target website. The target site will not know that the request is from you or a proxy server, thus preventing your ip from being blocked by the site.
1. The agent masks the IP address of your crawling tool.
The main advantage of using an agent is that it allows you to remain anonymous when conducting all online activities.
2. Agents help you avoid IP blocking
After using a proxy, even if ip access is blocked, it can be easily solved by switching to another proxy server.
3. Agents can help you bypass the restrictions set by the target site.
Agents can help you resolve this limitation by distributing requests among multiple agents so that the target site can see that the request comes from different users.
4. Faster load time
The proxy server caches the data the first time you request it. The next time a request for the same data is received, the proxy server returns the cached data, saving valuable time and reducing the load time.
5. Better security
By using proxies, you can filter out malicious requests and users so that they cannot access your site. In addition to the other benefits discussed above, agents can provide you with an additional layer of protection.
