writes "During my last hotel stay, I thought it was a pretty strange that it took two browser re-directs before the hotel's Wi-Fi would show me the web page I browsed to. Picasa developer Michael Herf noticed the same the thing and dug a little deeper. He discovered: '...their page does some tracking of each new page you visit in your browser, outside what a normal proxy (which would have access to all your cookies and other information it shouldn't have, anyway) would do. This "adlog" hit appears to also track a "hotel ID" and some other data that identifies you more directly. Notably, I've observed these guys tracking HTTPS URLs, and of course you can't track those through a proxy.' Herf notes the Internet service provider, SuperClick, advertises that it 'allows hoteliers and conference center managers to leverage the investment they have made in their IP infrastructure to create advertising revenue, deliver targeted marketing and brand messages to guests and users on their network...'"
Herf was on his honeymoon when he did this sleuthing. Now that's dedication.
