title: What is the meaning of RollingFileAppender in log4net
body: <p>I read the documentation of it but I just don't understand it.It says:</p>
  
  <blockquote>
    <p>RollingFileAppender can roll log files based on size or date or both
    depending on the setting of the RollingStyle property. When set to
    Size the log file will be rolled once its size exceeds the
    MaximumFileSize. When set to Date the log file will be rolled once the
    date boundary specified in the DatePattern property is crossed. When
    set to Composite the log file will be rolled once the date boundary
    specified in the DatePattern property is crossed, but within a date
    boundary the file will also be rolled once its size exceeds the
    MaximumFileSize. When set to Once the log file will be rolled when the
    appender is configured. This effectively means that the log file can
    be rolled once per program execution.</p>
  </blockquote>
  
  <p>I am trying to find a way everytime I use the file appender a new file to be created but not to append to the same one.</p>
