Due - Monday January 31, 2011 - 11:59PM

The goal of this assignment is refresh your memory of socket programming and HTTP. For this assignment, you will complete Assignment 4: Web Proxy Server (http://media.pearsoncmg.com/aw/aw_kurose_network_3/labs/lab4/lab4.html) described in the Kurose/Ross text.

Description

1. For full credit, you must implement caching as described in the Caching section and #3 of the Optional Exercises.

3. If you use Java, your program must run as described on the assignment page: java ProxyCache port
4. If you use Java, you do not need to use the sample code provided on the website if you feel another design would be more appropriate.
5. If you use a programming language other than Java, you must include a README that clearly describes how to compile and run your program on the CS lab machines and a run script that will run your program on the lab machines.

Submission

1. By the deadline, all source code must be checked in to SVN at /<username>/cs621/lab1.
2. Late projects will receive a score of 0.
