Issue

I’m searching for a technique to avoid hotlinking on Azure, similar to how in AWS one may use waf and cdn to check for referer headers. Is it possible to accomplish this with Azure?
I also can’t utilise signed links since the user would have to reload the page continuously.

Solution

You could use Azure CDN Premium for it. It provides token authentication to prevent assets from being served to unauthorized clients:

There were also some discussion already here regarding the use of SAS Tokens. Combining short lived SAS Tokens and Content-Cache Header might work as well.
