What is cURL and how does it work?

For tech-savvy readers, cURL is an open-source command-line software written in C to support communication for the most important internet protocols.

Think of it as a versatile helper that knows many languages for communication with different parties. cURL lets you imitate the behavior of the average browsing session, like downloads and HTTP connection requests, but it can also be used to interact with APIs, remote servers, and other systems for testing, web development, and other crucial tasks.

cURL is mostly used to retrieve information from the web. For example, Linux users that interact with the terminal may download specific files or programs with a cURL command. Still, its greatest strengths are scripted interactions with intended websites. You can run a script that would imitate the monotonous behavior of an average internet user or enable data transfer between servers and other devices.

What is a proxy server?

If we plan to use these tools together, let’s briefly gloss over the functionality of proxies. Proxy servers are intermediary stations that adopt your connection requests as their own.

The true power of proxies comes from two factors: abundance and versatility. These servers have millions of addresses across all countries. You can use them to hide your IP address and access platforms that are unavailable for you or residents of your region.

Most proxy servers are separated into two different types. DataceAnter proxies are fast and run on good hardware in designated data centers. While the servers are well-protected from physical threats, the recipients of your connection requests will quickly notice one distinctive trait – the address is not connected to an internet service provider (ISP).

You can test your main address by visiting whatismyip.com. It will display your ISP, approximate location, and other information linked to your IP. After the connection to a proxy server, these personalized data parameters will change. Datacenter proxies have one fatal flaw: their addresses are structured into connected bulks, with no affiliation to ISPs. For recipient servers, it is a dead giveaway that the user is using a proxy.

Thankfully, there is a better solution – residential proxies. These servers share IPs with real devices that are serviced by legitimate ISPs. Residential proxy networks are slower, but top providers have millions of addresses in all countries.

cURL connections with proxy servers

cURL becomes an even better web tool with the help of proxy servers. With comfortable integration of the service through adjustable commands. The user can use the same command line to choose the desired server, enter login credentials, and change between proxy types.

With direct support for proxy connections, you can enjoy the efficient communication and automated features of cURL without exposing your IP address. This is crucial for situations where the user has no access to desired web servers due to location restrictions or a direct IP ban.

Summary

Proxy servers are the perfect partner for versatile connections and automated processes generated by cURL. With their help, you can explore the web and gather valuable information without exposing your identity. For best results, choose a designated provider that offers specialized cURL proxies. They will help bypass any internet blocks while keeping your identity safe for all cURL connections.
