IMO, it's the other way around.
"user-agent" is the real HTTP name of the variable. It's the variable name
that's acually used in the GET request.
"HTTP_USER_AGENT" is what CGI makes from it. Or what's used in the Apache
configuration.
So, it's in fact the cgi variables that should be documented in terms of
http headers.
Anyway, in Jason Hunter's servlet book, there's a list of these CGI
variables and their servlet counterparts.
