At present, many people are using HTTP proxy IP, but HTTP proxy IP for uncommon users do not know what HTTP proxy is, do not understand HTTP proxy IP only, do not know how to choose a good proxy IP, in fact, there are many small knowledge to choose HTTP proxy.
1. IP quality of free proxy is the worst
Used free HTTP proxy IP users are clear, using free proxy IP effect is very poor, really don’t want to use after a single use again in the second, but in fact, on the Internet to collect free IP with users, there are many, avoid is free at no cost, save the cost, but is actually spend more time trying to filter IP for free, but business is slow
2. Common HTTP proxy IP address
On many agent platforms, you can see regular IP proxies or open IP proxies, which can obtain a large number of IP addresses at once through the API interface. It is easier to use than free IP proxies, and the price is not expensive. In fact, common proxy IP addresses are filtered out after free IP authentication. Basically the same as free proxy IP
3. Crawler enhanced version of tunnel forwarding
In fact, many agents will name the dynamic forwarding proxy IP as crawler proxy IP, which makes many people think that crawler proxy IP is the dynamic forwarding proxy IP, but it is not the case. Dynamic forwarding proxy IP is crawler proxy IP, but crawler proxy IP is not only dynamic forwarding proxy IP, it can also be API proxy IP, through THE API link to obtain tunnel IP. Crawler is just a name, there are many dynamic forwarding products, such as crawler enhanced version of tunnel forwarding, crawler and so on.
