We are getting "Session has expired. Please, refresh the page." issue in the telerik report viewer while opening in IE8 browser. This issue only occurs in IE8 and SSO mode over SSL. The issue doesn't occurs in other version of IE browser like 10, 11 and in Chrome and Mozilla browsers. The application is hosted on IIS server. The report viewer is placed inside in a user control which is again placed in a user control and that is in a master page. The report viewer is getting bind on click of link button. Could you please suggest why are we getting "Session expired error". We also tried to analyse the issue in Fiddler but get the "SessionHasExpiredMessage" as below in Textview:
