azure cdn purge not refreshing cached content

I also found if you purge each file separately, for example, put /css/main.css in 'Content path' when purging instead of 'purge all' it will work

After working with Microsoft and Verizon Digital Media support for a number of weeks, they finally figured out the solution.

In order to avoid interfering with the purge process, the easiest method is to implement the following "IF" statement before the "Features" portion of your rule:

IF | Request Header Wildcard | Name | User-Agent | Does Not Match | Values | ECPurge/* | Ignore Case (checked)

This if statement will skip this rule altogether for requests made with the purge user agent, allowing the request to hit the CDN as normal.
