And, because I'm anal about security and relying on false info,
remember that the info set in $_SERVER['HTTP_USER_AGENT'] is provided
by the user. Sanitize the data properly, and have something built in
for if that data is absent.

I know you probably do all that, but if I don't warn someone about it
after giving that sort of advice, I get an itch in the back of my
skull that drives me crazy.
