403 Forbidden

Error message

403 Forbidden

What it means

Constant defining the 403 Forbidden response expectation: with expecting(SC_FORBIDDEN), a 403 response fails the request future instead of completing normally. 403 means the server refuses the request despite (or regardless of) authentication; the 'message' is the reason attached to the failure.
