Finish discussion of network chapter.

Topics :

• client / server socket programming : code/client_server (run on shannon)
• textbook's "echo server" (note: only handles one connection)
• the textbook's "tiny web server" : code/tiny_web_server (ditto)
• CGI and environment variables
• http packets illustrated

Start reading the next chapter, on concurrency : there are some tricky things in there. We'll discuss them after the break.
