Proxy

A proxy is a server that acts as an intermediary between a user's machine and another network, usually the Internet. It allows the user to retrieve data without revealing his IP address.

When a user makes a request on the Internet:

• The request will be directed to the proxy server.
• The proxy replaces the user's IP address with its own address and transmits the request to the application server.
• When the proxy receives the response, it sends it back to the user.

The following are the benefits of using a proxy:

• Privacy: by masking the user's identity.
• Speed: by caching files.
• Security: by filtering out certain malicious web content.
