Conditions

Conditions select the network requests to which a profile applies. Different condition types are combined with logical AND. Multiple enabled values within a condition usually broaden that condition; excluded variants remove matches.

Condition	Field
Request domains	requestDomains, excludedRequestDomains
URL filter	urlFilter
Regular expression filter	regexFilter
URL case sensitivity	isUrlFilterCaseSensitive
Initiator domains	initiatorDomains, excludedInitiatorDomains
Top-level domains	topDomains, excludedTopDomains
Domain type	domainType
Resource types	resourceTypes, excludedResourceTypes
Request methods	requestMethods, excludedRequestMethods
Tabs	tabIds, excludedTabIds
Tab groups	tabGroups, excludedTabGroups

Disabled or empty items do not contribute to a generated rule. If no conditions remain, the profile is global. Headerly always excludes its own extension ID from initiator-domain matching to avoid applying rules to itself.
