Proxy Server
A Proxy Server is a server that acts as an intermediary between the user and the Internet. When a user connects to a Proxy Server, his or her requests for access to Web sites are first sent to the proxy server, which server filters the requests and can provide different levels of functionality, privacy, and security depending on the needs of the user or business.
In the context of digital marketing, Proxy Servers can be used for various purposes, such as testing ads in different geographical locations.
