Proxy is a communication interface in a network which works as an agent that takes one request and then connects to the other side. If the proxy as a network component is used, the other true address remains hidden which creates a certain anonymity.
As our prime motto is to make an average user used with the terminologies, like Proxy in this case, we can give an light example from daily life to make you understand how a proxy works. Suppose you have a sweet quarrel with your mother. But you need some information immediately from your mother. As if you ask you mother right now, she will straightforwardly drive you away saying, “why me! find it yourself somewhere.” You probably have done it really – simply get the information using your father. So, your father is working as a Proxy in this case. Quite obviously, there is a bit risk of the fact that, your mother might understand that actually you have asked it, and that chance of getting revealed or not is purely depending on your father – your proxy, how it can hide your ID and get the information and let you know. The thing is basically same with our this Proxy and proxy server.
Working types of Proxy – Default Proxy and Reverse Proxy
In case of default proxy, the client computers send their requests to the proxy not to the server. This server acts as an intermediary body to connect to the main web server.
In case of Reverse Proxy – proxy server forwards frequent identical requests from the Internet but not to the main Web server, but it works itself as if it has cached data stored. (Compare your father is saying – ‘I know it, no need to ask your mother as you brother asked through me the same thing in your situation!’)
