What is a Proxy Server?

Educative Answers Team

A proxy server acts as a channel between the user and the internet. It separates the end user from the website they’re browsing. This is useful for various reasons, which are touched on below.

Why use a Proxy Server?

Proxy servers not only forward user requests but also provide various benefits to the user, such as:

  • Improved security
  • Improved privacy
  • Access to blocked resources
  • Control on internet usage of employees and children
  • Cache data to speed up requests

How do Proxy Servers work?

Whenever a user sends a request for an address from the end server, the traffic flows through the proxy server on its way to the address. Similarly, when the request comes back to the user, it again flows through the same proxy server which then forwards it to the user.
