How to use cURL proxies?

Proxies are still considered the most reliable and effective method for quality scraping. It is thanks to the use of proxy server systems that multi-threaded grabbers will be able to work more efficiently with the system. Also, the proxy solves problems with optimization and speed of working with the network. The use of servers allows you to achieve greater stability of connection and protection of your personal data.

Why work with proxies?

Proxy servers act as a smokescreen: they mask your computer’s requests. They will actually be performed from an anonymous foreign IP address, which ensures maximum anonymity of the connection. The intermediary servers themselves make it impossible to block your account by IP. Thus, you, in fact, use an intermediary to work with the Network, which provides connections with servers through other remote servers. Using proxies for scraping is most effective if you need to process a colossal amount of data. With a complete reversal of cURL systems, you send a huge amount of information every second, so you can be blocked by the receiving server, but the proxy system acts as a shield that prevents you from being blocked. Blocking is usually related to protecting servers from DoS attacks. Using a proxy will make you protected from protection systems. Steps to connect:

1. The first thing you have to do is open the code in cURL.
2. Next, you need to enter the CURLOPT_PROXY parameters, but next to it you should provide the IP AND port values for the proxy server you are using.
3. 
4. Next, you need to write CURLOPT_PROXYTYPE, and next to it write down the type of proxy used. Do not forget to specify the relevant constant data typical for working with the “cURL system”.
5. 
6. Next, use the request function to specify the site you are going to access using proxy servers.
7. 
8. Next, decide on the time limits, after which the system will determine that the request was processed incorrectly or it did not arrive.

How to choose a proxy?

First of all, you should pay attention to the complete anonymity of proxy servers, since through transparent servers it will be possible to read your real IP, which is why the system can block you. Personal anonymous servers are considered to be of higher quality, which do not allow you to determine the real location of their owner. The system can determine that you are using a proxy, but it will not be able to determine who you are.
