Watching The Web

So there I was, minding my own business, working on a piece of code I had to deliver that evening, when the pretty dark-haired girl who sits in the cubicle behind me popped her head over and asked for my help.

"Look", she said, "I need your help with something. Can you write me a little piece of code that keeps track of Web site URLs and tells me when they change?"

"Huh?", was my first reaction...

"It's like this", she explained, "As part of a content update contract, I'm in charge of tracking changes to about thirty different Web sites for a customer, and sending out a bulletin with those changes. Every day, I spend the morning visiting each site and checking to see if it's changed. It's very tedious, and it really screws up my day. Do you think you can write something to automate it for me?"

Now, she's a pretty girl...and the problem intrigued me. So I agreed.
