Browser Cache Settings
Most browsers think they are smarter than the user and want to cache certain portions of a web page and present them to the user. This does not work for dynamic web applications that use java script to build web pages. AVNOC is java script based and requires the browser cache to be turned off.
The Server sets a timeout limit for inactivity in the Engineering Portal. When the timeout limit is met, the server invalidates the session and issues a 404 error code.
Refresh your browser to reset the session.
