Buy me a coffee. Become a Patron. It assumes that you are a professional PC user and by no means a professional system administrator. Also, you will be able to create as many proxy logins and passwords for your friends and family as you want. I basically assume that your knowledge and background is more or less similar to mine, when I just started learning about Linux. Why make your own proxy-server? There has been a lot of controversy recently regarding the government censorship of the Internet, especially in the CIS region.
What is a proxy server
Proxies and VPNs differ in nature, although they can provide some of the same services. A VPN routes all of the network traffic on a client computer through a tunnel to some other server computer. No individual application configuration is required. In contrast, using a proxy requires each application to be individually configured to ensure its traffic goes through the proxy. The intent of a VPN is to allow a remote client computer to access network resources in some other location as if it were physically located in the same office. One of those network resources can be access to the internet, which masks the IP address of the remote computer.
A step by step explanation for non-technical users
In the days of firewalls, VPN services and the Tor application, practical methods of masking the IP address and speeding up the Internet, a proxy server is becoming indispensable for actively surfing the Internet. Many users use a proxy without really thinking about what it is, how it works and what functions it can perform. Below we will analyze what a proxy server is, where to get it and how to start using it. We will also focus on such points as the specifics of choosing a server and the differences between anonymous and regular types. The term proxy comes from the Latin "proxus" and means "next" or "substitute".
A Squid Proxy Server is a feature-rich web server application that provides both reverse proxy services and caching options for websites. This provides a noticeable speedup of sites and allows for reduced load times when being utilized. Squids reverse proxy is a service that sits between the Internet and the webserver usually within a private network that redirects inbound client requests to a server where data is stored for easier retrieval. If the caching server proxy does not have the cached data, it then forwards the request on to the web server where the data is actually stored. This type of caching allows for the collection of data and reproducing the original data values stored in a different location to provide for easier access. A reverse proxy typically provides an additional layer of control to smooth the flow of inbound network traffic between your clients and the webserver.
