title: Identify if request is coming from local network (intranet)
body: <p>I need to identify if a request comes from Internet or Intranet using either client-side or server-side.</p>
  
  <p>The problem I'm trying to solve is: our web site can be accessed from internet and intranet. The intranet user (user inside company), does not have access to internet. We are using Google Anylitics, when intranet user access the page, the page take so long to upload because it tries to download (ga) JavaScript file generated from Google.</p>
  
  <p>Any solution?</p>
