Just discoverd that one can't connect to two notebooks server at the same time if they are (both?) over https.
Login to another notebook server make the cookie invalid for the first server, not actually preventing you from executing code
but preventing you from dooing stuff like saving.
(not expecting answer until pycon is over of course...)
Can you edit this issue to focus on one thing? I would post the comment on #883 in that issue. Also, the last question is not clear what you mean.
Yes, the second and third paragraphs where to ask if I should open another issues, i might not have been very clear sorry about that.
punting this cookie issue to 0.14.
