At the end of my controller function, I'd like to log the user out and send him back to the login screen, hopefully with a response.flash on the screen.
I've tried several things, none of which work.
I tried sending him to URL(c='default',f='user',args=('logout')) which
got close. One was summarily dropped to the home page, with no
feedback as to how one got there.
Any suggestions?
