Cannot send error with Custom LoginUrlAuthenticationEntryPoint

[Angel]

Hi, I have extended LoginUrlAuthenticationEntryPoint in order to send an Error code in certain situations instead of redirecting to the login page, but the error status is not being set.

public class AjaxAwareAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint {
	
	private static final Logger logger = LoggerFactory.getLogger(AjaxAwareAuthenticationEntryPoint.class);

	@Override
	public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) 
			throws IOException, ServletException {
	
		if(request.getHeader("ajax") != null) {

			response.sendError(HttpStatus.SC_REQUEST_TIMEOUT);
		}
		else {
			super.commence(request, response, authException);
		}
	}
}

I am setting up the header in an ajax request from the client, the header is being set properly and response.sendError, but I never get the error code on the other end.

I am injecting the custom entry point in the <http> element of the spring security namespace.

I am using JQuery on the client side.

What am I doing wrong?

Thanks,
Angel

Nevermind, the problem was the specific error code I was sending.
