Here's a question for the computer experts. I got curious (well, nosy, maybe) and looked up an old high school friend on the internet. I found quite a lot of info, in fact, on several pages. I'm not planning to contact her, or use this information in any way, other than to satisfy my own curiosity.

My question is this: Can she tell that it was me, specifically who looked at her web page and other pages with references to her? If not, how much could she tell?

And what about the ethics of doing this at all? Justifiable or no?
