Meta-data
It's data about data. There's nothing non-data about it.
If I were an opposition party leader, I'd be rather nervous if someone from my household started browsing www.wierdsextoysrus.com and the URLs requested were available to the government. It doesn't matter that they don't save the image data. http://www.wierdsextoysrus.com/images/huge-prickly-prober.png is probably enough to ruin a life.
