ASP.NET Session Timeout Issue with ReportViewer in an iframe

Shende1, Pankaj 0

I'm using the following setup to load SSRS reports with the <rsweb:ReportViewer> control in an ASP.NET web application:

<rsweb:ReportViewer 
    id="RptViewer" 
    runat="server" 
    width="100%" 
    skinid="rv" 
    ProcessingMode="Remote" 
    ZoomMode="FullPage">
</rsweb:ReportViewer>

My web.config session settings are configured like this:

<system.web>
   <sessionState cookieless="UseCookies" mode="InProc" timeout="20" cookieSameSite="None" />
</system.web>

We're using .NET Framework 4.8 on a server in a web farm setup. When loading the ReportViewer via an iframe, we're encountering ASP.NET session timeout errors.

Could this issue be related to the ReportViewer's support for iframes? Do we need a custom HTTP handler to maintain the session across the iframe?

If anyone has faced a similar issue, your guidance would be greatly appreciated.

Does your server provide sticky session? Please note that the ReportViewer uses the ASP.NET Session. Since your Session is InProc, web farm will have to provide sticky session.
