Purpose: Identifies requests that were referred by a hostname that matches a pattern defined by a wildcardThis type of value supports the use of special characters to establish a pattern. For example, specifying an asterisk within this type of value will match one or more characters. value.

Key information:

• The hostname associated with the referrer through which content was requested determines whether this condition is met.

• The value(s) associated with this match condition may be defined using any combination of numbers, letters, and/or symbols. This type of value also supports the use of special characters.

  Each specified value may contain one or more asterisks. Each asterisk will match a sequence of one or more 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."

• Specify multiple hostnames by delimiting each one with a single space.
• The Ignore Case option determines whether a case-sensitive comparison will be performed.
• The Result option determines whether this condition will be met when the referring hostname is a "match" or does not match the specified value(s).

• Due to the manner in which cache settings are tracked, this match condition is incompatible with the following features:

  • Default Internal Max-Age
  • Force Internal Max-Age
  • Ignore Origin No-Cache
  • Internal Max-Stale
