What is proxy and its uses?
Proxies are one of the very useful computer  networking techniques, used by many computers these days especially for  the internet connection networking. Proxy server is basically and  application program which is commonly known as a server, used to service  the clients requests so as to forward it to other available servers. 
       The client is connected to the proxy server,  which requests for some services involving the request of files,  connections, web pages, and many other resources which are available  from the other different connected servers. 
       The caching property of the proxy server is very  useful for the internet, as it can process and return the result of a  request without even being in contact with the destination server, this  is achieved by using the content which had been saved earlier by the  client's request. The proxies with the caching ability keep the copies  of the latest and the frequently visited resources saved in the network  memory so that they can be used later on. This also allows the ISP or  the internet service providers to reduce the usage and costs involving  in the networking so as to elevate the over performance. 
       The main purpose of the proxies is to connect to  the available server so as to provide with the resources, on the behalf  of the client. The proxy sever also has the option of altering the  request of the client or even the response of the server approached.  Sometimes the proxy server can also process the request without even  contacting the sources server. The proxy server which can pass all  requests and reply unmodified is also known as the gateway or sometimes  the tunneling proxy. 
       Proxy servers can be used to place address in  the local computer of the user which connects the user and the  destinations server or the internet.
