How can I get the HTTP status code out of a ServletResponse in a ServletFilter?

Question

I\'m trying to report on every HTTP status code returned from my webapp. However the status code does not appear to be accessible via the ServletResponse, or even if I cast

Answer 1

Also need to include a wrapper for #sendRedirect, and it would be better to initialize status to '200' rather than '0'

private int httpStatus = SC_OK;

...

@Override
public void sendRedirect(String location) throws IOException {
    httpStatus = SC_MOVED_TEMPORARILY;
    super.sendRedirect(location);
}
