Hi Himanshu,
Seems still have HTML cache exist. Maybe session, maybe cookie, maybe something else.
I think it should be possible to set a breakpoint when login to Facebook by checking "keep me login" button, you would be able to know where the data goes. Or try to find the documentation on Fackbook for how they manage the user account storage in WinJS.
Probably clean the
sessionState object ?
