a.k.a. anonymous surfing
Proxy surfing is a technology that allows users to surf the Internet without others knowing where you have been, what you have done, or what you have seen. Proxy surfing also enables you to get around certain restrictions that may have been placed upon you by your employer, school, or governmental body.
When you use an anonymous proxy server, your browser doesn't contact a Web site directly. Instead, it tells a proxy server which Web sites you want to visit. The proxy server then contacts the Web site, and when you get the Web site's page, you don't get it directly from the site. Instead, it's delivered to you by the proxy server. In that way, your browser never directly contacts the Web server whose site you want to view. The Web site sees the IP address of the proxy server, not your PC's IP address. It can't read your cookies, see your history list or examine your clipboard and cache because your PC is never in direct contact with it. You're able to surf without a trace.
There are Web sites, for example, that allow you to surf the Web anonymously by entering the URL into their search box. Incidentally, the owners of these sites will not know who you are because they do not save any cookies or tracking codes. No one else will know who you are either including the owners of the sites you visit, or your network administrator or ISP.
