Chapter 6: Definition Reference

define url.domain condition
Binds a user-defined label to a set of domain-suffix patterns for use in a condition= expression.
Using this definition block allows you to test a large set of
server_url.domain= conditions very
quickly. Although the
define condition definition block could be used in a similar way to
encapsulate a set of domain suffix patterns, this specialized definition block provides a substantial
performance boost.
For domain and prefix definitions, the manner in which the URL patterns and any condition
expressions are listed is significant. Each line begins with a URL pattern and, optionally, one or more
condition expressions, all of which have a Boolean AND relationship. Each line inside the definition
block is considered to have a Boolean OR relationship with other lines in the block.
Syntax
define url.domain condition label
domain_suffix_pattern [condition_expression ...]
...
end [url.domain condition label]
where:
•
label—A user-defined identifier for a domain condition definition. Used in a condition=
condition.
•
domain_suffix_pattern—A URL pattern suitable to the url.domain= condition, that includes
a domain name (domain), as a minimum. See the
url= condition reference for a complete
description.
•
condition_expression ...—An optional condition expression, using any of the conditions
available in a rule. For more information, see Chapter 3: "Condition Reference". The layer and
timing restrictions for the defined condition will depend on the layer and timing restrictions of the
contained expressions.
The
condition= condition is one of the expressions that can be included in the body of a define
url.domain condition
definition block, following a URL pattern. In this way, one domain definition
block can call another condition-related definition block, so that they are in effect nested. See the
example in the
define condition definition block topic.
