Microsoft ReportViewer - ASP.NET Session Expired

Question

This question is related to Microsoft ReportViewer: Expired Errors . Unfortunately, the accepted answer does not solve my problem. The subject of the report is a farm with several workflows running in each application pool. Session Mode - SQL. I have implemented IReportServerConnection.

The problem is that the session expires immediately. I can duplicate this in one field, so I assume that this is related to several workflows. I use RDL files, and I don't think ReportViewer even requires a session. So my questions are: how do I get rid of this error? If this is by disconnecting the session for reportviewer, how to do it? I thought the implementation of IReportServerConnection would handle this. The documentation seems sparse. Any help is appreciated.

Here is the exception and stack trace:

Message: ASP.NET session has expired
Process name: Microsoft.ReportViewer.WebForms
Type: Microsoft.Reporting.WebForms.AspNetSessionExpiredException
StackTrace: at Microsoft.Reporting.WebForms.ReportDataOperation..ctor () in Microsoft.Reporting.WebForms.HttpHandler.GetHand string operation type) in Microsoft.Reporting.WebForms.HttpHandler.ProcessRequest (HttpContext context)

Answer 1

I ended up installing AsyncRendering for False. I read this solution, but was hoping to find an alternative. There may be other options for web gardens / farms, but this is the only thing I could come up with for the limited time I had to look for.
