Make a program that downloads from a web server a web page.  Make sure the download was successful.  Time how long it takes.

Due:  Fri March 5

Points:

333,333 Can extract a hostname from the URL
333,333 Reads the URL from the command line
333,333 Can tell if there is no hostname becuase the URL is stupid/malformed
000,001 Can find a web site that takes longer than 0.5 seconds
1,000,000 Can download the web page from the web server
1,000,000 Can tell if the download failed because either not a 200 error code or read/write failure.
1,000,000 Can compute the time it took.
----------
4,000,000 total


Notes:

Time does not include how long it takes to open the socket.
Time should have units.  Don't say 12.3, say 12.3ms.

The hostname of http://www.server.com/fred/wilma.html
	From the 7th char to the first '/'
	Between the 2nd and 3rd '/'
	You can use string or arrays of chars (but one is better)
	Array people want to know about strchr()
	String people want to know about find()
