Declan, Thought you'd be interested in this. While playing with Zero Knowledge Systems' new Freedom 3.0 privacy product, I noticed that it actually notifies Zero Knowledge whenever you start it up. It sends a bunch of HTTP requests (through the M$ IE subsystem, no less) to ZKS. Here's a sample header: GET http://www.zeroknowledge.com/client/3/redirect.asp?pid=2029&prn=0&ver=3.0.0&lang=en&event=1&url=1 User-Agent: Mozilla/4.0 Plus all the standard HTTP stuff -- IP address, date/time, etc. This would also include any cookies set from zeroknowledge.com, (which ZKS sets every time you go there), but I filter cookies through the MEconomy system, so I had none from them. What's "pid" (I checked -- unrelated to my Win 2K process ID)? What's prn? What's "event"? Why is s it being sent back to zeroknowledge EVERY time I start up Freedom? Guess even the privacy good guys want to track you. ********
