Proxy Servers

In Computer's era you will frequently hear the term written above that is proxy and proxy servers. Proxy servers are basically acting as a layer or intermediary for the requests of the clients to the server. The basic functioning of the proxy server is that they accepts the request of the clients, processes the request after applying filters and after that if the request is validated it asks the server to fulfill the filtered or formatted requests.

It might be a case that the proxy servers doesn't even contact the specified server for the clients request like asking for files, connection or any other resource. A proxy server may optionally alter the client's request or the server's response. The main purpose behind use of proxy servers is mentioned below:

1.To hide the identity of the client (anonymous):

Mainly this is done for security purposes so that the server that is being asked to fulfill the requests of the client may not be able to trace the client or to hide the identity of the client especially for the areas where clients deal with transactions of money, security of a country, etc.

2.Another important benefit of the proxy servers is to speed up the access to the resources on the server because of its popular feature of caching the content that is asked again and again by the client.

3.Also many institutes or the companies use proxies to avoid or ban or block  the undesired websites that they doesn't want in their network to be opened. (But remember my friend If They use proxy servers to ban sites the people of their network are also smart enough to use the proxy server to access blocked contents.)

4.Proxies can also be used to bypass the security levels available in the network like parental control.

5.Proxy servers can also be used to scan the remote servers for malware before delivering the contents to the clients.
