Subject: mod_ruby HEAD message

Is it possible (and sensible) to change cgi.out to handle HEAD messages 
with the following;

def out(options = "text/html")

   options = { "type" => options } if options.kind_of?(String)
   content = yield

   if options.has_key?("charset")
     require "nkf"
     case options["charset"]
     when /iso-2022-jp/ni
       content = NKF::nkf('-j', content)
       options["language"] = "ja" unless options.has_key?("language")
     when /euc-jp/ni
       content = NKF::nkf('-e', content)
       options["language"] = "ja" unless options.has_key?("language")
     when /shift_jis/ni
       content = NKF::nkf('-s', content)
       options["language"] = "ja" unless options.has_key?("language")
     end
   end

   options["length"] = content.length.to_s
   output = stdoutput
   output.binmode if defined? output.binmode
   output.print header(options)
 >>
   exit (Apache::OK) if defined?(MOD_RUBY) && Apache.request.headeronly?
<<
   output.print content unless "HEAD" == env_table['REQUEST_METHOD']
end
