*Exactly* what I am looking for. Strange that I haven't encountered that
little feature before. I've wondered why the HttpServletRequest can
return an immutable Map. Eh. Well, it's a big API, and I assume you
learn something new everyday, even if it's propably something rather
basic that I should've known by now.
Thanks also for the rest of your comments. Very informative.
