body: <p>location A: web server<br>
  location B: file server</p>
  
  <p>location A and B connected via DSL.</p>
  
  <p>User in location B selects a PDF document linked from a webpage served from web server in location A. Will the PDF document be upload from loc. B to loc. A and then back transmitted to loc. B to the user which requested the document?</p>
  
  <p>Or is it possible that the requested document will be directly sent to the browser of the user located in location B without transfering the PDF document from location B to location A and then back to location B?</p>
