I can only find information on the X-Forwarded-For header for the Verizon Premium CDN. Does the Azure CDN or any of the others included the X-Forwarded-For header? If not is it possible to add it?
Hello
@Christian
You are right, Azure CDN Premium from Verizon supports X-Forwarded-For header
https://learn.microsoft.com/en-us/azure/cdn/cdn-verizon-http-headers
Azure CDN also supports X-Forwarded-For header
https://learn.microsoft.com/en-us/azure/cdn/cdn-msft-http-debug-headers
https://learn.microsoft.com/en-us/azure/frontdoor/front-door-http-headers-protocol#front-door-to-backend
You may also restrict the set of accepted values for the header 'X-Forwarded-Host' sent by Azure CDN from Microsoft.

I tried to add the X-Forwarded-Host through rule engine and got the below error:
Rules validation failed. More information: Header "X-Forwarded-Host" is not allowed to be modified by the rules engine.
Any clue, how I can add this one please?
