Programming Assignment 2

Write an HTTP Proxy server

• One or more web browers should be redirected to your server.

• All requests from the browser should go through the proxy. If the requested file is cached on your proxy, return it immediately. Otherwise, pass the request on to the appropriate web server.

• When a requested document is returned from a web server, make a copy of it, and pass it back to the requesting client.

• Your proxy server should maintain a logfile called proxylog with a line for each event, including the following.
  • requests from clients, including the client ip address (in dotted decimal notation), the name of the server, the name of the file, the time that the request was made, and whether or not the file was in the proxy server cache and thus returned immediately.
  • all responses from remote servers

From the Tools menu, choose Internet Options
