Re: [racket-users] How to disable back button in web application

I haven't had the time to test it, but I am wondering if calling (clear-continuations-table!) which send/forward does will delete all continuations, even those of other users. So suddenly links that other users want to use will also get wiped out. I probably won't have time to test today, but
