When i init ajaxmanager ajaxRequest from client side radprogressmanager starts its unstoppable progress callbacks and overloads IIS. Please find the attached code to reproduce the issue. Run App and run chrome/ firefox debugger, wait for 2 mins for timer to init ajax request as required and then you can see radprogress unstoppable callbacks.
Hi, By analyzing the code you have provided it is not clear where you are calling the startSaveDraftTimmer Function. It is declared but not called. Therefore there the reason for ISS being overloaded does not seem to be provoked by the AjaxRequest. In addition please note the limitation of XmlHttpRequest component provoking the users from using RadUpload with AJAX calls.
