在一个ASP页面停留的多少时间的程序

ASP Source Code:


----------------------------------------------------------------------
<% If Request.QueryString("time") = "" Then %>
You haven't clicked on the link below yet.<BR>
<% Else %>
You spent <%= DateDiff("s", Request.QueryString("time"), Now()) %>
seconds looking at the previous page.<BR>
<% End If %>
<BR>
<A HREF="time.asp?time=<%= Server.URLEncode(Now())%>">How long have I
spent on this page?</A><BR>
<BR>
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.
