Referring Domain

Purpose: Identifies requests that were referred from the specified hostname(s).

The hostname associated with the referrer through which content was requested determines whether this condition is met. An option is provided to indicate whether this condition will be met when the referring hostname "Matches" or "Does Not Match" the specified value(s).

Key information:

• Specify multiple hostnames by delimiting each one with a single space.
• This match option supports special characters.
• If the specified value does not contain an asterisk, then it must be an exact match for the referrer's hostname. For example, specifying "mydomain.com" would not match "www.mydomain.com."

• The Ignore Case option determines whether a case-sensitive comparison will be performed.

Sample Scenarios

The following table provides sample scenarios for this match option.

Value	Description
www.domain.com	This pattern will be satisfied when the request was referred by a URL whose hostname is "www.domain.com" (e.g., http://www.domain.com/index.html).
