title: Azure CDN Caching Index.html
body: <p>I have a custom domain pointing to a static webside using Azure CDN. After a deployment my website was no longer showing up. This was because and old version of index.html was being served from the CDN itself.</p>
  <p>I fixed it by purging the CDN manually, but this is not ideal because I frequently update the files for this website  via a build process.</p>
  <p>What is the best practice to avoid this outcome? Do I need to add a purge to the build process itself or is there a better way?</p>
