Proxy

What is a proxy server?

A proxy server is a computer that acts as an in-between for end user devices and any outside web address. In CEDP the proxy server is used for content filtering. When a device tries to access an external IP address, it is first routed through the proxy server. The server then checks whether the site is blacklisted or white-listed.

If it is white-listed then the site is allowed and is displayed on the end user device. If the IP address is blacklisted, the site will not be displayed and a message from CEnet will appear saying that access to the site is blocked.
