Program 3 Testing
=================

CS 455 - 90 points
CS 555 - 100 points

Requirements:

1) [5 points] Take a port (higher than 1024) as the only command-line
argument. This port is what the server will listen for requests on. If
given no command-line argument, print a "Usage" statement and exit.

2) [5 points] For each new connection, display the client's IP address and port.

3) [10 points] For each request, write the current date/time, client's
IP address and port, and the requested URL to a text file named
'proxy-log.txt' - one request per line.  Example:  
10/23/2007 14:53:40 EDT 128.82.5.53 51617 http://www.cs.odu.edu/~mweigle/

4) [10 points] Print the request header received from the client.

5) [10 points] Modify the request as needed. Your proxy server should
not send any request header fields that do not start with "Accept",
"Cookie", "Host", or "User-Agent". Print the modified request header
that is sent to the server.

6) [10 points] Print the response header received from the server.

7) [10 points] Your proxy server must keep processing requests until the user
quits the program with Ctrl-C.

8) [15 points] Your proxy server must handle all types of requests and
responses, including those for images.

9) [10 points] Your proxy server must manage connections according to
the default specifications for HTTP/1.0. (One connection per
request/response.)

10) [5 points] Your source file must be named HTTPProxyServer.java

-----------
Write the answers to the following questions in a file named Prog3.txt
and submit it with your source code: 

1. Request a URL with your HTTP client from Program 2. What was the
response time?

2. Modify your HTTP client from Program 2 to use your proxy server
(send the request with the full URL in the GET line and connect to the
proxy server instead of the web server). Request the same URL as above
using the proxy server. What was the response time?

3. Were these response times different? If so, why?
