1.Proxy caching allows the server to act as an intermediary between users and Web content providers. When a user visits a web site, the proxy interprets and responds to requests on behalf of the original server.
For most modern Web, requests to Web services are handled by intermediate servers. This intermediate or proxy server processes requests to determine how they should be handled. Proxy servers allow businesses to build and secure their networks while providing additional functionality transparently to users.
