title: Safari problems accessing Windows Integrated Authentication (aka NTLM) protected web site
body: <p>Our web application uses Windows Integrated Authentication (aka NTLM Auth) for security.</p>
  
  <p>It's working fine for both IE and Firefox users, but Safari users are seeing intermittent problems.  Browsing the site will work fine, but every once in a while there will be problems loading elements of a page (e.g. CSS or JS files).  Reload and the problem will go away.</p>
  
  <p>If we use a debugging proxy (Fiddler) we can see that there is a lot of extra 401 requests happening with Safari.  Every once in a while a request for a resource will get stuck in a 401 request loop, and eventually fail.</p>
  
  <p>I can't see anything that we're doing to cause this, and it would appear that it's a bug in Safari.  Has anyone ran across this issue before, and have any suggestions for a resolution?</p>
  
  <p>Thanks,</p>
  
  <p>Darren.</p>
