There several ways to do what you want.  E.g. you may use 
variables in the error page specified, e.g.

   error_page 413 /413.$var.html;

or use an error_page with additional processing for the page in 
question, e.g.

   error_page 413 /413.html;

   location = /413.html {
       if ($new) {
           rewrite ^ /413.new.html;
       }
   }
