Disabling echo from webrick

Question

How can I disable messages from webrick echoed on to the terminal? For the INFO messages that appear at the beginning, I was able to disable it by setting the Logger parameter so as:

s = WEBrick::HTTPServer.new(
  Port: 3000,
  BindAddress: "localhost",
  Logger: WEBrick::Log.new("/dev/null"),
)

But I further want to disable the messages that look like:

localhost - - [17/Jun/2011:10:01:38 EDT] "GET .... HTTP/1.1" 200 0 http://localhost:3000/ -> .....

when a request is made from the web browser.

Try setting AccessLog to false in the config parameters, that is as far as I can see by [the source code](http://www.ruby-doc.org/stdlib/libdoc/webrick/rdoc/classes/WEBrick/HTTPServer.html#M009708). — Yet Another Geek, Jun 17 '11 at 15:29
@Yet Another Geek I tried both setting it to false, then to nil, but it did not work. — sawa, Jun 17 '11 at 15:33
@Yet Another Geek. When I set it to `[nil, nil]`, it worked. Your link helped. Thanks. — sawa, Jun 17 '11 at 15:39

Following the link to the source and suggestion provied by Yet Another Geek, I was able to figure out a way. Set the AccessLog parameter to ~~[nil, nil]~~ [] (Changed following suggestion by Robert Watkins).

s = WEBrick::HTTPServer.new(
  Port: 3000,
  BindAddress: "localhost",
  Logger: WEBrick::Log.new("/dev/null"),
  AccessLog: [],
)

Actually, you're better off passing an empty array for the AccessLog - e.g. AccessLog: [] Passing in nils just results in an error, which you can't see because you've sent your error logs to /dev/null – Robert Watkins Feb 04 '13 at 06:50

Use `Logger: WEBrick::Log.new(File.open(File::NULL, 'w'))` for a cross-platform solution – ens Jan 11 '16 at 22:31
