Internet Proxies
Internet proxies are composed of proxy server which serves as a bridge between you and the internet. It’s an intermediary server that sits between end users and the websites they visit. Depending on your use case, needs, or company policy, proxy servers provide varying levels of functionality, security, and privacy.
When you use a proxy server, internet traffic passes through it on its way to the address you requested. The request is then routed through the same proxy server (with some exceptions), and the proxy server forwards the data received from the website to you.
Proxy Server Mechanics
Every computer connected to the internet requires a unique Internet Protocol (IP) address. Consider this IP address to be your computer’s street address. The internet knows how to send the correct data to the correct computer by using the IP address, just as the post office knows how to deliver your mail to your street address.
A proxy server is essentially an internet computer with its own IP address that your computer recognizes. When you send a web request, it first goes to the proxy server. The proxy server then makes your web request on your behalf, receives the response from the web server, and forwards the web page data to you so you can view it in your browser.
When the proxy server forwards your web requests, it can alter the data you send while still providing you with the information you expect to see. Because a proxy server can change your IP address, the web server does not know where you are in the world. It can encrypt your data so that it is unreadable while in transit. Finally, a proxy server can restrict access to specific web pages based on IP address.
