ReportViewer Session Expired error

Him

I know a lot of people suffer this issue in the past...
but in my case it's really hard to reproduce the session timeout error.
everything works fine, the user can see the reports etc...

this can works fine for days.
and suddenly a user can receive the timeout error, and only when he try to
export the report! (in PDF or Excel...)
if the user purge his internet explorer cache and export again, then it's
ok.

I have changed the expiration in IIS and in the web.config to 1 hour.
But the user come back few days later and the error is raised again!

the control is displayed in a page which is in a popup page and through an
IFrame
Popuppage -HTML page -IFrame -ASPX page -Reportviewer
but also I have tried this:
Popuppage -HTML page -FrameSet -ASPX page -Reportviewer

I add a timestamp in the HTML page and the ASPX pages
/reports/viewreport.html ?t=<timestamp>
/reports/runreport.aspx? t=<timestamp>&o ther parameters...

So this insure that IE don't cache the pages, but the error still here!!!!!

I'm out of ideas and the error is really random and only when I export.
The SP1 of the reportviewer control is applied.

Thanks for your help if anybody know how to solve this.

Hi, Could somebody please tell me how I check whether a session is dead based soley on the Session.SessionID. At present the timeout is set to 20 minutes in IIS, I am aware that I can reset this on the page. However after 22 minutes, or some interval longer than the session timeout, the Session.SessionID values is still availible. What I want to achieve is this. There is a small section of my site that must have an active session....

I have developed a web portal that uses ReportViewer web control to connect to a remote SQL 2005 Report server and displays the reports on the client side. The asp.net page has been coded to automatically impersonate a specific user who has access to the report server so that the customer don't get a pop-up asking for login credentials. Once the report has been displayed in the Report viewer control, I am getting an error when I click on...

I have a report that uses 2 datasets (2 tables on the report) VS2005 correctly generates 2 ObjectDataSource objs when selecting the report in the smart tag of the ReportViewer. Depending on values the user enter, example start/end date, the report must display only that data, so I have 2 classes that selects the data and return the relevant data sets (set up in the TypeName and SelectMethod properties of the ObjectDataSource objs).

I had this idea about preventing session fixation, and I'm wondering what anyone else thinks about it. The idea is, essentially, don't allow session ids that YOUR PHP didn't generate (and aren't yet expired) to log in. That way if someone sticks a made-up session ID on a URL, it won't matter, unless it happens to correspond to an active session (guessing a user password is probably easier). Is this already standard practice, new, or is...

I'm having issues with the reportviewer control. When viewing the regular report it works just fine. However, when an export to PDF or Excel is attempted and the load balancer sends the export request to another server I get the following error: ASP.NET session has expired It looks like the download goes to a page "Reserved.ReportViewerWebControl.axd" and tries to grab the report it just built but can't find it to download it.

Hope someone can help. We are trying to deploy an ASP.Net 2.0 application to a 3-node webfarm. The application uses the ReportViewer control in local mode, hence we need session state. Because we dont wan't a single point of failure we use SQL Session State. I have setup a persistant sql session state database on a SQL 2000 server (this is a cluster in production, so no SPOF) I have setup our web.config files to include; " <sessionState...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
