title: Logging to local file with Application Insights
body: <p>Can Application Insights log to a local file in the application directory? We have an implementation where each customer who uses our software needs to have a separate instance of Application Insights. Our client software relies on a call to a web service to get the Instrumentation Key. We are running into some issues where we need logging before we get the Instrumentation key. </p>
  
  <p>Can Application Insights log to the local file system? Or can it cache logs such that they can be explored? Thanks.</p>
