Assignments, Projects, and Exams
- Homework 1: Problems 6, 7, 13, 14, 18, and 20 from Chapter
1 in the text.

Due: October 19, in class.
- Homework 4: The assignment is to create a filtering web
proxy. This proxy should take HTTP requests and check the URL
against a list contained in a file read by the proxy when it is
started. If the URL matches some element of the list, do not
forward the request; instead, return either an error code, or a
small image that you have stored locally. You may use any
language you like. You may also use the java code provided as
part of the text material in Programming Assignment 4 in
Chapter 2 of the text. At the very least, I expect you to
demonstrate a working proxy. For full credit, make your proxy
obey wildcarding, so that if a line in the list reads "*/ads/*"
any URL that contains the string "/ads/" will result in the
error code or local image being returned. Please turn in your
source code and a MD5 hash of the compiled executable. On that
day, we will schedule demonstrations of your code, and I will
use the MD5 to verify that the code presented is what is being
run. If you need a platform to work on, please let me know.
Due: November 9th, before class.
