With the advancement of technology and the development of the Internet, more and more companies need to use proxies in their business. So why can't you crawl data using http proxies? Let me introduce it to you:
1. Poor IP quality
Using a publicly available and free http proxy has low availability, poor stability, low efficiency, and a small IP pool.
2. The network is not stable
If the network is unstable, the proxy IP will naturally fail to crawl data. The unstable network of the user client, the unstable network of the proxy server, the unstable network of the client and proxy server network nodes, or even the unstable server of the target website that the user browses to are all reasons that lead to network instability.
3. Too many concurrent requests
When using a web crawler proxy IP, if the number of concurrent requests sent by the crawler is too large, it may cause the server to timeout and fail to crawl data. Therefore, users need to pay more attention to adjusting or controlling the reasonable number of concurrent requests.
4. IP is unavailable
Using the same proxy IP to crawl the same site will cause the IP to become unavailable.
The above is the reason for using a highly anonymous proxy IP. I hope it can solve everyone’s problem!
