 -	Filter on the values for the incoming header '**X-Forwarded-Host**' sent by Front Door. The only allowed values for the header should be all of the frontend hosts as defined in your Front Door config. In fact even more specifically, only the host names for which you want to accept traffic from, on this particular backend of yours.
-    - Example – let’s say your Front Door config has the following frontend hosts _`contoso.azurefd.net`_ (A), _`www.contoso.com`_ (B), _ (C), and _`notifications.contoso.com`_ (D). Let’s assume that you have two backends X and Y.

     - Backend X should only take traffic from host names A and B. Backend Y can take traffic from A, C, and D.
     - So, on Backend X you should only accept traffic that has the header '**X-Forwarded-Host**' set to either _`contoso.azurefd.net`_ or _`www.contoso.com`_. For everything else, backend X should reject the traffic.
     - Similarly, on Backend Y you should only accept traffic that has the header “**X-Forwarded-Host**” set to either _`contoso.azurefd.net`_, _`api.contoso.com`_ or _`notifications.contoso.com`_. For everything else, backend Y should reject the traffic.
