ref. previous entry "multiple usermin user via httpd reverse proxy - ID: 2831383" that I closed,
too soon I am afraid.
last night - hours after I logged on to close that call, several class users mentioned that the problem was "still happening". That is, they would log on as themselves - several "nearly simultaneously", and would receive their usermin display with a the username in the top lh corner of one of the other student/users.
When they refreshed, they would retrieve their correct details, and as long as there wasn't "too much" activity, most of the session threads seemed to stay "untangled".
Any suggestions on how I might assist you in tracking this down?
