027 | Proxy Servers: Your Reliable Network Middleman — Why You Need Them and How They Work

19.06.2025

In today’s internet-driven world, where data constantly travels between millions of devices, it’s often not enough to establish a direct connection — you may need a “middleman.” That’s where a proxy server comes in. It acts as a bridge between you (the client) and the destination resource (server), handling network requests on your behalf. Understanding how proxies work is critical for network security, optimization, and access management.

What is a Proxy Server?

A proxy server (from the English proxy — representative, intermediary) is a server in a computer network that acts as an intermediary between a user (client) and other internet servers. All client requests go through the proxy first, which then forwards them to the destination server. Responses from the destination server also return to the proxy first before being sent back to the client.
