Projects (mandatory!)

Project 1: Talk to the Server
Your project consists of building a tool to obtain a web object from a server.
Your tool should ask the user for the URL or the server's address and file path/name.
It then uses HTTP (over a TCP connection) to send a GET message and receive a response from the server, which is shown on the screen.
The deadline is 4/19 in the classroom, where you should show a demo and give me the code.
This is a group project, and each group should have 2 or 3 people.
You may use any computer (your laptop or a machine in the DC) and any programming language.

Project 2: Streaming
This project consists of researching a site related to one of the topics in the list below.
Start by selecting a topic from the list. Then find a product or site related to the topic and send the info to me by email.
To avoid repetitions, I will use FCFS.
After researching the the topic, you will write a 2-page paper about it, and present it to the class on 5/3, when the paper is also due.
Use ppt for the presentation and make it short, 5-10min.
Work alone or in groups of 2.

Project 3: Web Caching
Extend project 1 to implement a web proxy.
Your cache will receive requests from a browser.
If the requested page is not in the cache, get the page from the server (project 1), keep a copy in the cache, and send the page to the browser.
If the requested page is in the cache, send a if-modified-since GET to the server.
If the server asnwers yes, update the cache with the new page and send it to the browser.
If the server answers no, send the page in the cache to the browser.

Project 4: Paper
Choose a paper from WWW 11 or 12. Send me the title as soon as possible, FCFS!
A 2-page paper is due on 5/31, when you should also give a 5-min ppt presentation.
The presentation should include the problem, the solution, some interesting details, and results.
You can work alone or in a group of up to 3 people.
