(c) FileAppender

(d) DeleteAppender

I had been asked this question at a job interview.

I'd like to ask this question from Remote Logging in division Parsing, Benchmarking and Logging of JavaScript

Answer 1

Right answer is (d) DeleteAppender

The best explanation: There are several ways to log using “appender”s. Some of the current available Appenders are:

DummyAppender: log nothing.

ConsoleAppender: open a new window in the browser or an inline div element and insert log messages in real time.

WindowsEventAppender: send log messages in the MS Windows event manager (Internet Explorer only).

FileAppender: write log messages in a local file on the client (IE and Mozilla).

AjaxAppender: allow to send log messages to a remote server with asynchronous HTTP request.

MetatagAppender: add log messages as meta data.

JavaScript Console Appenders for Opera, Mozilla and Safari.
