List Of Free Proxy Software and Web Proxy Servers To Browse Anonymously

For example, if you are accessing Google from your computer using a proxy named X, your computer is not receiving information directly from Google but X is receiving services and send it back to your computer. So naturally the web server does not know your computer and it thinks it served X. So by using a proxy server, theoretically you can browse anonymously and also help you to bypass firewall restrictions too. This guide gives a short introduction of Proxy Servers with a number of popular server addresses. There are two types of Proxy services.
