Add option to detach specific files from the Azure Front Door dynamic cache
When you host a SPA (Single Page Application) on an Azure Blob storage with Azure Front Door (with dynamic caching activated):
Everytime you release a new version of the app, users have to force-reload the page in order to get the new version.
Because the links to the new assets (like main.***.js, ...) are located in the index.html, which has been cached.
I was able to solve it:
1. Let the Azure CLI set the Cache-Control header to "no-cache" on the index.html after pushing it to the blob storage:
az storage blob update --account-name $(storageAccount) --container $web --name index.html --content-cache-control no-cache
2. Purge the Front Door cache:
az network front-door purge-endpoint --resource-group $(ressource) --name $(frontdoor) --content-paths "/"
Would be much better if you add an option to except files from getting cached.
