title: Is SNI actually used and supported in browsers?
body: <p>I can find various information about SNI (see <a href="http://en.wikipedia.org/wiki/Server_Name_Indication" rel="noreferrer">Wikipedia</a>), but I can't find any statistics about actual support in browsers.</p>
  
  <p>The best I could find out is that it should work on Windows XP with SP3.</p>
  
  <p>Does anyone know if SNI can actually be used in practice?</p>
