  script_tag(name:"insight", value:"The error page mechanism of the Java Servlet
  Specification requires that, when an error occurs and an error page is
  configured for the error that occurred, the original request and response are
  forwarded to the error page. This means that the request is presented to the
  error page with the original HTTP method. If the error page is a static file,
  expected behaviour is to serve content of the file as if processing a GET request,
  regardless of the actual HTTP method. Tomcat's Default Servlet did not do this.
  Depending on the original request this could lead to unexpected and undesirable
  results for static error pages including, if the DefaultServlet is configured to
  permit writes, the replacement or removal of the custom error page");
