 you would prefer to defer creating the log file?

Hi Everbody=2C
=20
I=92m looking for a way to defer the creation of the log file until the fir=
st entry is logged. I want to use log4net for writing protocols for jobs th=
at can be executed in my application. With my current configuration the fil=
e is created during startup which makes no sense if the job doesn=92t run. =
=20
=20
My current configuration:
=20
      <appender name=3D"=85" type=3D"log4net.Appender.RollingFileAppender">
        <file value=3D"....." />
        <appendToFile value=3D"false" />
        <rollingStyle value=3D"Date" />
        <datePattern value=3D"yyyy_MM_dd.\tx\t" />
        <staticLogFileName value=3D"false" />
        <threshold value=3D"INFO" />
        <layout type=3D"log4net.Layout.PatternLayout">
          <conversionPattern value=3D"%date=3B%level=3B%m%n" />
        </layout>
      </appender>
=20
One possibility seems to be to generate the appender programmatically=2C bu=
t then I lose a lot of flexibility. Another one is writing my own appender =
(or subclassing an existing one). Is there another way ?
=20
Any help is appreciated=2C
