Hi,</div>

<div style="font-family:Tahoma,Geneva,sans-serif;font-size:12pt;color:rgb(0,0,0)">
I want to dynamically add (and eventually remove again) loggers to a system.  The idea is that based on specific events (e.g. a flag in a HTTP REST request header), the logs for this request are written to a separate file (in addition to writing to the usual
 log file).  I also want to modify the log-level for this request to TRACE - ideally just for the messages written to the dedicated log file.  Is configuring a SiftingAppender the correct approach for that? And does anyone have some sample code they could share? 
 Any help/feedback is greatly appreciated!</div>
