If a user is on your website and opens another link (also to your website) in a new tab, is it possible to differentiate this from the user just clicking on the link normall
The short answer is, no. The long answer is, if you are doing an ajaxy call from your pages to server-side methods, that could keep ttrack of the windows open (called within a short timeframe). It would be a sloppy, unreliable mess, and you couldn't differentiate between a new window or a tab for that matter.
