A proxy server is often used when the client and the server are incompatible for direct connection (for example, when the client is unable to meet the security authentication requirements of the server but should be permitted some services).
A proxy server is located between a client and a server where it acts as an intermediary between the two, such as a Web browser and a Web server. The proxy server’s most important role in providing security.
Example of usage – “A client initially connects with a proxy server to send a request, such as accessing a file or opening a Web page. The proxy server filters and evaluates each IP address and request. The verified request is forwarded to the relevant server, which requests the service on behalf of the client.”
