問題文

The error handling page states what happens when an error handler passes the request on. Which pair of statements does the page make?

選択肢

1. The same handler downstream runs a second time, so a guard against looping is required.
2. The next error handler downstream is reached, and passing the throwable along or leaving it out makes no difference.
3. No handler downstream gets a turn, because the exchange ends at once with a server fault.
4. The first standard handler downstream is entered, and its own logic decides what to send back.
