What is a Proxy Server?

A proxy server can speed up your internet connection if you are for example in a company people can surf the internet using a proxy server. When the first user visits site A the server saves the record and when the second user visit the same site the user number two will take its information from the proxy locally and not from the internet.

Companies can use proxy servers to filter or block sites that they don’t want people to visit or even whole countries can use proxy to filter out sites.

People also use proxy server in other location for example a person wanting to visit YouTube.com from Thailand needs to find a open proxy server in for example in USA and then he can surf YouTube because his IP will be from USA.
