 1. In Frontends/domains, select `+` to open "Add a frontend host". Give your host a name - this needs to be a valid, unique subdomain of the domain `.azurefd.net`. Choosing a name based on your custom tracking domain should help to ensure uniqueness; you should see a green check mark appear on the right. (We will change this later to be your actual custom domain.)

 1. Next, we create a backend pool that contains just the SparkPost tracking domain. In Backend pools, select + to open Add a backend pool. Give this a name.

     * The backend host header field will be automatically filled in for you. Leave the HTTP port and HTTPS port settings at defaults. Click Add.
 
     * Leave the Health probe inactive, as there is only one backend.
 
+    * This will forward the `Host` and `User-Agent` HTTP headers to SparkPost properly, which is necessary for Engagement Tracking to work as expected.

 1. On "Routing rules", select `+`. Give your rule a name.
 
     Leave "Accepted protocol" as the default "HTTP and HTTPS". Ensure your "Frontends/domains" setting is your previously configured subdomain name.
 
     Set the Path to `/*` to match all incoming requests. Leave Route type set to the default "Forward", and set Forwarding Protocol to "Match request". Select "Add".
