title: Azure CDN rules engine to rewrite default document and remove .html extension
body: <p>I would like to use azure blob and CDN <a href="https://cdn.windowsazure.com/http/rules/default.aspx" rel="noreferrer">premium features</a> but the <strong>documentation is very sparse</strong>. This is something totally doable on Amazon S3 / CloudFront.</p>
  
  <p>For clarity I want <code>*.azureedge.net/sample/index.html</code> to equal<code>*.azureedge.net/sample/</code> and <code>*.azureedge.net/sample/test.html</code> to equal to <code>*.azureedge.net/sample/test</code></p>
  
  <p>This is totally not clear and takes "up to 4 hours" to preview changes, so...</p>

  <p>After some investigation, Azure has a wrapper for Verizon Edgecast CDN, and this page looks identical to theirs...</p>
