A proxy server acts as a middle-man or a relay between the two parties. Usually, proxy servers are either computer systems or routers that exists between a client and a server to prevent any cyber attack or other criminal invasion.

The proxy server is a system over the internet that can accept any incoming packets or requests from the client’s end and send it to its destination server. This proxy server will protect the identity by offering a different IP address every time. In the corporate field, it helps in keeping the system anonymous and restraint caching which improves speed.

How does a Proxy Work?

The proxy server responds to requests sent by the end-user, based on certain conditions. They are:

  1. If the requested data is not cached, the proxy server will retrieve the information for the end-user.
  2. If a requested data or page is cached, then the proxy will deliver it to the end-user.
  3. The proxy server will transfer client responses.

In other words, the proxy server performs both the roles of the client and the destination server, even though it is the middle man.
