Hi Dave-- There has recently been some discussion on both this list and the Net Neutrality Squad mailing list about ISPs modifying web traffic (e.g., the recent messages about Rogers modifying Google's home page). Related to this, I wanted to point you to a toolkit that a server could use to detect whether its pages are being modified in flight. The toolkit is available at the URL below: http://www.cs.washington.edu/research/security/web-tripwire.html The toolkit allows publishers to deploy "web tripwires" on their own web pages. Web tripwires are JavaScript code that can detect when a web page is modified in flight, so that the publisher is aware of the event and can notify the end user if appropriate. The URL above also has a brief summary of a measurement study that used a web tripwire to detect changes to a web page (http://vancouver.cs.washington.edu ). A message on your IP mailing list back in July helped draw users for the study. We'd be happy to get feedback on either the toolkit or the study results. Thanks!
