title: How to configure a log4j file appender which rolls the log file every 15 minutes
body: <p>I understand that i can use a DailyRollingFileAppender to roll the log file every month, day, half-day, hour or minute. But how can i configure log4j to roll the log file every 15 minutes.</p>
  
  <p>If this is not possible by configuration, please suggest/direct me on how to extend log4j's file appender to achieve this.</p>
  
  <p>Thanks and Regards.</p>
