A proxy website is that which allows you anonymnous surfing. IF u visit any website through proxy site then ur original Ip wont be shown to webste owners. Some people use proxysites to surf websites which are banned in their office.
Hi , one I use is proxyireland(DOT)com .. In our office , most sport and news sites are blocked.. But when using the proxy site.. The domain for the proxy shows up in logs , not the actual sites you visit :0)
Well, it probably would not block anything from your boss, if he does tracking it would appear that you are just visit one site and that is the Proxy site. The sites you however visits will show that the proxy site is the visitors and not you. Of course, if you type in a username/password or enter your email address on the site, they will know it is you behind the proxy. Proxy can be good for some, like in my case, my ISP DNS Servers get propagated very slowly and may take a few days before I see changes so I use a Proxy site to check on the changes. Some people may use proxy for proper purposes and some may use it to surf illegal websites such as porn or do something bad anonymously.
