I can make SAGE popup a "are you sure you want to leave this page" dialog when you try to navigate away. It is trivial to implement -- I did it once and forced myself to use it for 2 miserable days -- it's horribly annoying. That said, SAGE doesn't kill a running worksheet process until several *minutes* after all web browsers that are viewing it have stopped viewing it. It's not an immediate thing, or something that happens immediately on closing the browsing. > Also, from what I understand, worksheets are kept alive by the > "polling" > of the client?

True, but again, you would have to loose your connection for several *minutes*. > This makes me think that a checkbox "this worksheet is persistent" > might be better. That's definitely a reasonable proposal. What would you want it placed in the interface? One possibility is to put it in a hackish location initially, and put it in a separate worksheet configuration page later once such a page is implemented (I started on it but ran out of time). > Obviously, this option should not exist on servers that serve a wide > range of users. > It's really for people doing big computations on their own set of > computers.
