How to add proxy to Ubuntu

First of all we need to understand what is proxy and how does it work.

What is a proxy?

A proxy or proxy server is basically another computer which serves as a hub through which internet requests are processed. By connecting through one of these servers, your computer sends your requests to the proxy server which then processes your request and returns what you were wanting. In this way it serves as an intermediary between clients & resources

Why add Proxy to Ubuntu

There are many purposes to add proxy to Ubuntu

1.      it is used for tunneling firewalls and anonymous surfing

It keeps the computers behind it anonymous (mainly for security) by hiding (IP addresses, port, etc) from hackers.
It speeds up access to a resource by caching.
One internet connection can be used by more than one computer using proxy.
Proxy servers will have a list “proxy list” to filter the unwanted contents (you can modify the contents).

Note:

There are some proxies which are free and some which charge money, the choice is up to you but we have found that the paid proxies are more reliable, faster and more secure.
