Sadly, I think I made a horrible mistake pulling mod_wombat into httpd
core (as mod_lua), and need to unwind that some so it can be used by
folks today :-(

But, assuming you are using httpd 2.3 (unstable) series, you can
access the CGI variables through the subprocess_env table on the
request, so for a typical handler:

function handle(r)
  local remote_addy = r.subprocess_env["'REMOTE_ADDRESS"]
  -- do stuff
end
