body: <p>I have seen a number of questions that don't answer this, is it possible to check someones bandwidth using java script and load specific content based on it?</p>
  
  <p>The BBC seem to give me low quality images when using my mobile and in the middle of nowhere.</p>

  <p>Does anyone know how they do it? or how I could do it using asp.net or javascript, or an community opensource plug in.</p>
  
  <p>I think it may be possible with <a href="https://github.com/yahoo/boomerang/" rel="noreferrer">https://github.com/yahoo/boomerang/</a> but not sure this is its true purpose.</p>
