Address filter element. Optional in <rule> elements. Overrides attribute::ClientAddressFilter when the rule is applied.




Comma-separated list of IP addresses. Each individual address may include an optional netmask suffix to allow specification of IP address ranges. See [attribute::ClientAddressFilter](../../../../../ir-api/material-cat/image-rendering-api-ref/c-ir-material-catalog/c-ir-attributes-reference/ for details.


Access to this image catalog can be restricted to one or more specific IP addresses by specifying them in an <addressfilter> element. A "request refused" error is returned to the client if the client IP address is not matched.
Access is not restricted if <addressfilter> is empty or not specified.
If the <expression> in the <rule> element is absent or empty, the <addressfilter> is applied to all requests.
localhost is always implicitly part of the ClientAddressFilter definition, even if not explicitly specified. Requests originating from localhost are never rejected, regardless of the ClientAddressFilter specification.
