When a user wants to access the Internet, the service provider assigns an IP to the user. This IP is saved by the websites the user accesses. Some Internet users think that this method is not safe; so, they may resort to different ways. Proxy technology enables access to the Internet via a proxy server instead of directly via the main server. In this way, users can hide their identities and navigate the Internet safely. Also, a strong proxy can protect users from different kinds of threats on the Internet.
