A proxy agent is a system that creates an opportunity for a server to be connected to various devices and users. For example, a server cannot connect to some IP addresses that are not included in its functional domain. Thanks to proxy agents, it is possible to share data between private devices and a server. A proxy agent is an intermediate member of sharing information on the Internet. A crucial feature of it is that this service provides the security of a server. Users that are connected to the server through a proxy agent cannot see the original address of the server. They are only familiar with a proxy service. As a result, the chances of the server being attacked are much lower than usual.
