Proxy Site
5 Apr 2010
In computer networks, a proxy server is a server (a computer system or an application program) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.
A proxy server has many potential purposes, including:
* To keep machines behind it anonymous (mainly for security).
* To speed up access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.
* To apply access policy to network services or content, e.g. to block undesired sites.
* To log / audit usage, i.e. to provide company employee Internet usage reporting.
* To bypass security/ parental controls.
* To scan transmitted content for malware before delivery.
* To scan outbound content, e.g., for data leak protection.
* To circumvent regional restrictions.
A proxy server that passes requests and replies unmodified is usually called a gateway or sometimes tunneling proxy.
A reverse proxy is (usually) an Internet-facing proxy used as a front-end to control and protect access to a server on a private network, commonly also performing tasks such as load-balancing, authentication, decryption or caching.
proxy is very effective to smoothen the road network within a single connection. by proxy we can accelerate our internet network connection. once the proxy is closely connected with the port. without the port, the proxy will not run. with the proxy server site servers we can change, depending on where it originated proxy site.
