I made a small change to the compile_support.rb file to check for a nil case for env["SERVER_PROTOCOL"] as it was causing a problem when I moved my project to jRuby running inside jBoss.

Thanks for all the great work on prawnto, it makes my code a lot cleaner!

@vfrride This change also fixes rendering problems with pow webserver and 2.3.x rails apps

Can be also expanded to:

          @controller.request.env['SERVER_PROTOCOL']        =~ /^https$/i ||
          @controller.request.env['HTTPS']                  == 'on'       || 
          @controller.request.env['HTTP_X_FORWARDED_PROTO'] == 'https'
