SYMPTOM:
Users may want to have a report services document running with no session expiration. To do so, users can set the document auto refresh with an interval less than the Web User Session Idle Time on Intelligence Server and Session Timeout on Strategy Web server. With these settings, the session will never timeout technically.
However, after running the document for a very long time e.g. 20+ hours, users may still get the session timeout error on Internet Explorer 11 with Strategy Web 10.11.
STEPS TO REPRODUCE:
1. Create a report services document with several panels. Insert ESRI map to each panel. Create a panel selector for these panels.
2. Set Document auto refresh for every 4 minutes in document's advance setting. The auto refresh interval must be smaller than the web user session idle time(10 minutes by default) and the session timeout on IIS(20 minutes by default)
3. Access to IIS. Right mouse click on the web application pool, choose Recycling, disable the Regular time intervals(in minutes) so that the application pool will not recycle. Restart IIS.
4. Run the document on Internet Explorer 11 with presentation mode, notice that the auto refresh works well and the session is still alive after several hours' idle time.
5. However, if keep the document running for 20 more hours and click the panel selector to switch panels, it will pop out the session timeout error.
6. If run the document for much longer of the time like 30 or 40 more hours, the auto-refresh will fail eventually and the Intelligence Server session will be closed automatically.
