AJAX

Hi all,

I am using Ajax.dll in my web application.I need to refresh a page for maintaining a session more than one hour, So I created a ajax method that will be called for every 15 mins.

Suddenly it throws an error

System.NullReferenceException: Object reference not set to an instance of an object. at Ajax.AjaxRequestProcessor.Run() at Ajax.AjaxHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I thought the error might be in Ajax dll.

Can anyone please help me to get rid of the issue please.
