Title:
HorizonMiddleware class causes excessive session rewrites and possible
race condition resulting in logouts
Status in OpenStack Dashboard (Horizon):
Fix Released
Bug description:
the horizon middleware is checking for timestamps and modifying
last_activity for nearly every request.... this is bad in the case of
ajax requests for a couple of reasons...
A) ajax requests can be an order or magnitude greater than regular
requests.... making the session backend get thrashed.
II) if you try to switch project context from a page where you have
several longer running ajax requests going on, it is possible the
longer running ajax requests will update your session with older
tokens. The user will seem to be logged out at this point, and
really frustrated.
