I have the following code in doFilter() method, where I get application scoped bean.
I mapped 503 code to specific error page in web.xml. And I really get content of error page in browser, if error occurs. But the address in address bar doesn't change for error page address: an address of requested
servlet leaves there. Is it right behaviour?
I'd like to inform explicitly about redirection to error page. Is it only possible with sendRedirect() and sendError() is not useful here?
