Visit Duration Calculation in ASP

[chaneguye]

Hi

I want to calculate exact visit duration to an asp page of my website. Is there anyone out there who can help me in doing this. I prefer classis ASP code but if the solution is available in ASP.net, it will be OK.

I cannot rely on session_onend event because it does not trigger whenever user closes web browser without formally terminating session.

Thanks in advance.
