title: CSS not being applied on non authenticated ASP.NET page
body: <p>When developing (works fine live) the pages for our website don't pick up the correct CSS until the user has authenticated (logged on).</p>
  
  <p>So the Logon and Logoff forms look bad, but once inside the site, the CSS works again.</p>
  
  <p>I'm guessing it's some kind of authentication issue? Haven't really looked into it too much because it's only when working on dev so not a huge issue, but would be nice to know how to fix it.</p>
