Why is information collected by reptiles called servers? For example, if a store has a gift giving event and you go to the store 70 or 80 times an hour, of course the store will not give you any more gifts, but if you change your dress so that the store can recognize you, it will be ok. The same is true for crawlers using proxy servers.
1. Many sites identify crawler behavior. If you determine that your behavior is crawler, you will lock your servers and you will not be able to crawl any information.
Slow crawls down appropriately to reduce the strain on the target site, but this can be particularly inefficient, so it's best to use proxy servers.
2. Break through the anti-crawler mechanism and continue high-frequency crawler by setting the proxy servers.
Proxy servers is simply to let the proxy server to help us get the content of the web page, and then back to our computer, the choice of proxy is to choose a high hidden proxy.
Create an servers address pool. Try to create an servers address pool and rotate servers addresses evenly.
