ReportViewer Microsoft.Reporting.WebForms.AspNetSessionExpiredException RRS feed

  • Question

  • This error occurs in an MVC 3 vs10 and an MVC 4 vs12 application which is running on Server 2008. 
    It is NOT cookieless, it is NOT using Report Server it is using reports in the Local mode.

    It seems to happen when someone leaves the report open on their browser and goes home for the night.  I then get the exception about every 20 minutes or so.

    I know how to google, please don't refer me to random posts. 
    This is probably the best post from 2006 that shows all the people who have this issue.
