Report Viewer ASP.NET session has expired I am using a reportviewer control on an Aspx page like so: Page------ <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> <rsweb:ReportViewer ID="rptEvent" runat="server" Width="98%" ShowExportControls=False height="11in" visible=false /> Web.Config---------- <sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="120" /> Sometimes I get the following error and can not find out what is up. In some of the comments I see on-line list solutions that are not within my control dealing with IIS setup. I was wondering if anyone else was running into this and how can it be corrected? Thank you for any help!! ASP.NET session has expired Description: An unhandled exception occurred during the execution of the current web request.

Hi, I'm guessing this is on IIS7. To get this working you have to add a Handler mapping, which can be done via the IIS Manager or by hand like this: <system.webServer> <handlers> <remove name="WebServiceHandlerFactory-Integrated" /> <remove name="ScriptHandlerFactory" /> <remove name="ScriptHandlerFactoryAppServices" /> <remove name="ScriptResource" /> <add name="Reserved-ReportViewerWebControl-axd" path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler" resourceType="Unspecified" preCondition="integratedMode" /> <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </handlers> Notice that it goes below <system.webServer> All the best, Mark
Mark; Thank you for the reply!! I don't think I have control over this part of the IIS environment. I have the page and the web.config file that I can change. Is this something developers can change when in a shared environment through DiscountAsp.net? I want to stress the control only loses the session sometimes. When you reload the page it captures another session and is off and running again. It is enough to cause some concern.
...If you have access to the root web.config that is all you need for this. If you need help let me know. All the best, Mark
