title: Log current page url with NLog
body: <p>I'm trying to log the current pages URL as part of our NLog layout. I've scoured the NLog layout variables and have come up with nothing.</p>
  
  <p>Does anyone know how to get the current page URL as a variable for the layout? Also is it possible just to extract the domain name so this can be used in the EventLog source attribute?</p>
