Well, not between HTTP requests, as you surmised. I guess if I had to
implement something like you are describing, I would store the state from
before and after the change somewhere that the user can't see. I.e., store a
copy of the old objects and a copy of the new objects in some "transaction"
table in the database. If the user wants to revert, then I would delete the
new objects and re-populate the old objects. Or something like that.

Hope this helps,
