<% If Request.QueryString("time") = "" Then %>
You haven't clicked on the link below yet. 
<% Else %>
You spent <%= DateDiff("s", Request.QueryString("time"), Now()) %>
seconds looking at the previous page. 
<% End If %>
 
<A HREF="time.asp?time=<%= Server.URLEncode(Now())%>">How long have I spent on this page?</A> 
 
This script passes the time in a QueryString parameter. You could just as
easily store it in a session variable, log it to a database, or write it to
a text file. It all depends upon what you intend to use the information
for.
