title: Internet explorer: Official status of userData behavior?
body: <p>I've been having trouble with the <a href="http://msdn.microsoft.com/en-us/library/ms531424%28v=vs.85%29.aspx" rel="nofollow">userData</a> behavior in IE9, which I use when an IE version that doesn't support the Web Storage spec is encountered. </p>
  
  <p>Specifically, values don't seem to be saved when the .save() function is executed (in fact, there isn't even a userData folder in <code>C:\Users\USERNAME\AppData\Roaming\Microsoft\Internet Explorer\UserData</code>
  , nor is it created upon executing the .save()). </p>
  
  <p>I did some research and the consensus, from a handful of comments on various sites, is that it seems to be disabled in IE9. </p>
  
  <p>Is there some sort of official statement expressing this? If so, is there a way to test whether a given IE version supports it (without browser sniffing)?</p>
