Can bounce time (via back button) and access via bookmark be known?

[seashell]

Two questions:

Is it possible to know how much time someone spent on your homepage until they hit the back button? I realize bounce rate is usually measured by no additional clicks on a site within 30min - it assumes the person left - but is there anyway via javascript to know if a person left via the back button, and how many seconds?


Second, is it possible to know if a person accessed your site via a bookmark they had saved in their browser (for your site) earlier (assuming any cookie has long been deleted) ???

OK, for the second question, apparently IE looks for the favicon, which is the main way to tell its from a bookmark? Is that sorta close?

And for the first question, if the page was "referred" from a bookmark, the only way to capture that is with a javascript tag in the page?

A somewhat basic way of checking who came from a bookmark is adding something like this to your bookmark url

http://www.yoursite.com?b

Then you check your referral logs to see how much traffic comes in in that url
