Microsoft ReportViewer: Session Expired Errors
问题 The project is ASP.NET 2.0, I have never been able to reproduce this myself, but I get emails informing me it happens to clients many times a week, often a few times in a row. Here is the full error: Exception Details: Microsoft.Reporting.WebForms.AspNetSessionExpiredException: ASP.NET session has expired Stack Trace: [AspNetSessionExpiredException: ASP.NET session has expired] at Microsoft.Reporting.WebForms.ReportDataOperation..ctor() at Microsoft.Reporting.WebForms.HttpHandler.GetHandler()
