When user connect from our client web application to Arcgis Server, this require an initial authentication (login/pwd) which will be valid for, let's say 60mn as per Arcgis server settings.
After this period another manual user authentication will be needed from client side.
I would like to get, from Arcgis Server logs, the number of time a manual authentication occurred (per user, for statistics purpose). However looking at the various Arcgis Server log I cannot see how I could get this information.
Any idea?
