Request domains
Request-domain conditions compare against the domain of the requested URL.
Start here
Request domains are usually the condition that best matches the intended scope. Prefer them when matching the destination website; they are simpler than URL and regular-expression filters, support multiple enabled values, and match subdomains automatically.
requestDomains
The rule matches only requests whose destination domain is in the enabled list.
excludedRequestDomains
The rule does not match requests whose destination domain is in the enabled list. Exclusions take precedence over included request domains.
Entries contain domain names only, not schemes, ports, paths, or query strings. Headerly extracts the hostname when a URL is pasted. Subdomains of an entry also match. Values must be ASCII; use Punycode for internationalized names.
Example: example.com also matches api.example.com.
Use Initiator domains to match the site that started a request, rather than its destination.
