While making requests to a server you never thought how that request gets fulfilled .
For ex : If you are accessing the Gmail its main server will be out of India so if its out of india how the processing is so fast that we get data in less than seconds.
This is possible because of proxy servers.
Main server can be very far away from the request or may be busy with additional works which makes our request fail if it goes to the main server because of server time unavailability.
For solving this problem and for providing right kind of load balancing the proxy servers are assigned which contain the replica of information the main server have.
For ex : The Gmail server will provide the Indian people data to the Indian server and the Indian server will provide the state people data to the State server.
So replica gets created in many places and when user change its detail the replicas also gets updated.
