A proxy server is a computer that functions as an intermediary between the Internet along with the user’s computer. As shortly as getting such request, the proxy server will seek from the cache in its local hard disk for the resources. In the event the resources are cached they will be returned by the proxy server to the client computers. If not cached, it’s going to link to the servers that are important and request the resources on behalf of the client computers. Subsequently it ‘caches’ resources from returns, and the distant servers following requests for the exact same content.

Now, we use proxy server for assorted function like sharing Internet connections on a local area network, conceal our IP address, execute Internet access control, access blocked sites and so forth. Bellow are some advantages why individuals use proxy server:

Families and some small businesses have several computers but with just one Internet connection, they’re able to share Internet connection for some other computers on the LAN using a proxy server.
To accelerate Internet browsing.
This really is mainly for security reasons, to conceal the IP address of the client computer so it can browse anonymous. A proxy server can behave as an intermediary between the user’s computer along with the Internet to prevent from sudden access and assault.
To execute Internet access control like authentication for on-line time control, bandwidth control, Internet connection, Internet web filter and content blocker etc.
To circumvent blockers and security restrictions. For example, many work offices have blocked myspace and facebook yet, you may use proxy server to avoid such limitations and access blocked sites readily.
To circumvent limitations that are regional. For instance, a server using IP-based geolocation to limit its service to a particular state may be obtained using a proxy found in that state to obtain the service.
