define server_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 quickly test a large set of
server_url.domain=
conditions.
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.
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.

URLs” in Chapter 9 of the Configuration and Management Guide.
Note:
This condition is for use in the
<Forward>
layers and takes into account the effect of any
rewrite( )
actions on the URL. Because any rewrites of the URL intended for servers or
other upstream devices must be respected by
<Forward>
layer policy, conditions that test the
unrewritten URL are not allowed in
<Forward>
layers. Instead, this condition is provided.
Syntax
define server_url.domain condition label
domain_suffix_pattern [condition_expression ...]
...
end [server_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 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, that are allowed in a
<Forward>
layer. For more information, see Chapter 3:
The
condition=
condition is one of the expressions that can be included in the body of a
define
server_url.domain condition
definition block, following a URL pattern. In this way, one
server_url.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. Any referenced
condition must be valid in a
<Forward>
layer.
