Question from @pierrick22 via Twitter:

What's the fastest (more performant) way to replace storage url with a CDN url?

Hi,

You could consider the following suggestion:

Please make sure:
a) The CDN is created on the same storage account you have uploaded the exe to.
b) Please check if the Container to which the file is uploaded is a Public Container. Only blobs that are publically available can be cached with the Azure CDN. To make a blob publically available for anonymous access, you must denote its container as public. Once you do so, all blobs within that container will be available for anonymous read access. 

You could refer the following link for details:

Hope this helps.

Malar.
