Some CDNs support domain fronting, which allows connections to your site through a third-party domain. For example, by setting the connection address to visa.com and the Host header to my-domain.com, the provider will only see a request to visa.com.
You can configure this in the subscription settings. There are two options:
- Resolve address — used for SNI.
- Replace host — used to replace the actual Host header.
You can leave either of these fields empty; in that case, the name in the URL will be used.
The feature will be included in version 2.3.52.
