Definition - What does Proxy Server mean?

A proxy server verifies and forwards incoming client requests to other servers for further communication. 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 is providing security.

Techopedia explains Proxy Server

Network intelligence has advanced with the development of enhanced tools and network services such as the proxy server.

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.

A proxy server is used for many purposes, including:

To provide internal system security
To speed up resource access
To apply access policies for tracking organizational Internet use or assessing employee progress.
To bypass special controls, such as parental or security controls
To scan for viruses and malware
To circumvent regional restrictions
To allow websites to make requests to externally hosted resources when cross-domain restrictions prohibit websites from linking to outside domains
