Summary18975: Administrative user logout when rapidly refreshing question or group preview

When previewing in a question / question group / survey as a survey administrator and you rapidly refresh the preview window, eventually you will receive a 401 permission denied due to being logged out.

On further inspection, it appears for each refresh of the preview page, the session id is regenerated, see: and

eventually the session id becomes out of sync with the current page load in the browser, so it appears the user has been logged out (although the last session remains sitting on the server)

Steps To Reproduce

Steps to reproduce

preview a question as an administrator
refresh the page preview page rapidly

Expected result

Actual result

preview eventually displays a 401 and the admin user becomes logged out / disconnected from session
