title: How to suppress request logging to STDOUT in rails development server?
body: <p>More precisely, I want all <code>logger.info/debug/etc</code> messages to be shown only in *.log file, but not in console window. Thanks.</p>
  
  <p>UPD:<br>
  I dont want suppress all of console output, E.g. I want use <code>letters</code> gem to put my own output to console, also I want to use <code>debugger</code> which wont work with <code>stdout</code> redirected to <code>/dev/null</code>. I just want rails do not output <code>Rails.logger</code> messages to <code>stdout</code> (requests, <code>ActiveRecord</code> SQL queries, etc), Actually I can see such messages in log-file if needed.</p>
