Add functionality to Application Gateway for routing based on HTTP headers
The ability to route traffic to backend pools depending on HTTP headers would be much appreciated. At the moment the only way to do this is with a function app.
valid suggestion subject to customer upvote

this would be possible if we could at least rewrite the Host header, but somehow it is not supported.
this is definitely something we need for canary deployments
