Recently I was reading the MCTS ASP.NET 3.5 exam preparation book. I finished the lesson about web parts. The author said that user personalization is stored in a database and tracked by a cookie in a web browser.
I checked the database - it's there.
It seems however that the personalization information has noting to do with a cookie. It is recognized across multiple browsers. I even tried deleting all cookies and the webparts state are the same across browsers.
Do you have any idea WHY is that and HOW does it work without a cookie?
This may shed some light on how, Web Parts Personalization Overview, you basically setup SQLServer as the provider to manage the personalization data
