How Proxy Servers Work?
lReceive a request from a Web browser, perform the request, and return the results to the browser
lThe request may be performed after some authorization checks
lExample:
–You request  http://somesite.com/home.html
–Browser sends the request (GET http://..etc) to the proxy
–The proxy contact that “somesite” and issues a GET request
