How to Alert user before end of ASP session

[schick]

I need to alert my users prior to their asp session expiring. I would like to allow them to click a button to extend there session. Is this possible? What are my other options. Any help is appreciated.

Thanks,

Josh

I can't help with the code, but with the idea.
After the page load use javascript for a client side counter. There is a time or timer object as I remember. Set it using current session time. For example

var session_time = <%=current_session_time%>;

When counter is zero (or any value you like in this case) a messagebox should appear and ask for extra time. Cancel should retun(false), OK should send some parameter to the current page. Something like

document.location = 'page.asp?sessiontime=<%=current_session_time+extra_session_time%>';

At the beginning of the page put something like

if request.querstring(&quot;sessiontime&quot<>&quot;&quot; then
session.timeout = cint(request.querstring(&quot;sessiontime&quot)
else
session.timeout = 30 ' default
end if

' Also set some other default values
extra_session_time = 10
current_session_time = session.timeout

Let me know if it works.
