That sounds like a good solution.
As for the exit() - it's not required in all circumstances. What it
does is stop execution of the script immediately. If, for instance, the
redirect is the last thing in the file, exit() doesn't do anything good
or bad. However, if it's earlier in the file and you have other code
which might be executed, you want to call it (if you wanted to execute
the rest of the code you shouldn't be calling header() this early, anyway).
So it's not absolutely required - but I normally put it in to ensure any
further code isn't executed. And I normally put it at the end, also -
just for consistency (and in case I add more stuff later).
