ASP.NET session has expired strange error
Posted on 2012-09-10
I have ReportViewer controls on several Visual Studio 2008 pages and whenever I choose a radio button to run the report, I immediately get an "ASP.NET session has expired" error right in the report viewer where the report should be showing up. The error is in just plain text, it is not the full screen ASP.NET session has expired error.
I do not think this is an issue with the session tiemout value in IIS as this error occurs immediately after I open a webpage and not after a period of time. I am running IIS 6 and I have the maximum number of worker processes in the web garden set to 1 in the Application Pool. The session timeout in the website that is beign used is set to 60 minutes.
