Proxy Server, from the English proxy - (authorized, representative), It is a server, responsible for the connection to the Internet. Its tasks include the storage of the most visited websites in the memory and hide the IP-addresses of network users. Thanks to the proxy server device, It is on the internal network nodes, not directly connected to computers on the Internet.
Opening websites through proxy servers
After selecting a website address browser connects to the proxy server, which is supported by a network, and sends a request for access to the selected page. If the proxy server has a current copy of the page, it sends it to our computer. If a copy of the page is missing or is not in its resources, proxy loads a page directly from the server, where it is, and creates a copy of it in their own resources.
