2)In the application we have popup's like lookUp screens for searching.If user click on image it display a small popup at that time the parent page session has to disable and for popup session has to start.if user is not doing any operations on popup for 10 min.we have to show the notification after 9min stating that your session will expire in 1 min plz click OK to continue.The user notification is for child page not for parent page.After completion of work in child page he will click close button then we have to enable the session for parent page with out postback.

I would suggest:Not to use Session as it consume server resource unnecessarily.
http://oauth.net/[^] can be used as alternative which can be used to generate tokens,
which in turn can be stored in cookies.

If you want to go ahead with Session,

after each postback enable javascript timer for 9 minute.
after 9 min display the notification with message may be browser popup,and when user clicks "OK";
send ajax request to one of server page to keep alive the session.

One way to do it
Use the JavaScript setInterval method to call a JavaScript function (that you create) every 30 seconds. When the JavaScript function has been called 18 times, use JavaScript alert method to display the warning message.

var intCount=0;
setInterval("YourFunctionToCount()",30000)

function YourFunctionToCount(){
intCount++
if (intCount==18) {
    window.alert ("Timeout Imminent");
    intCount = 0
    }
}

Remember to set intCount to 0 every time the user does any other activity on the page.
