thanks, everyone. A sandbox alone is not trustworthy enough. the problem is intrinsically pretty bad. public internet. And I want one user to make up a question for another anonymous user to answer. (this also means that 'javascript as sandbox' won't work.) User 1 inputs something like
User 2 may see
The '0.5' is obviously computed, based on what user 1 provided. I need to avoid user 1 inputting mischief. Finally, user 1 receives back what the answer was that user 2 gave and can check whether it was correct. because answers are not algorithms (the way questions are), I can easily sanitize what user 2 provides. Do I really have to write my own language and parser for this? no one else has? regards, /iaw
