X-Forwarded-Host (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-Host#Examples).
The matching logic is ..
- If the property is null or empty (default), all hosts(or lack of) are allowed.
- A value is compared using ordinal-ignore-case (excluding port number).
- Subdomain wildcards are permitted but don't match the root domain. For example, *.contoso.com matches the subdomain foo.contoso.com
but not the root domain contoso.com or multi-level foo.bar.contoso.com
- Unicode host names are allowed but are converted to Punycode for matching.

X-Forwarded-For (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For#Examples).
The matching logic is ..
- If the property is null or empty (default), any forwarded-for chains (or lack of) are allowed.
- If any address (excluding port number) in the chain (comma separated) matches the CIDR defined by the property.

X-Azure-FDID and X-FD-HealthProbe.
The matching logic is exact match.
