Chapter 2: Managing Content Policy Language
•Rules in [Rule] sections are evaluated sequentially, top to bottom. The time taken is proportional to the number of rules in the section.
•[Rule] sections can be used in any layer.
[url]
The [url] section type is used to group a number of rules that test the URL. The [url] section restricts the syntax of rules in the section. The first token on the rule line is expected to be a pattern appropriate to a url= trigger. The trigger name is not included. The [url] section replaces the [Prefix] section used in previous versions of CPL)
•Rules in [url] sections are evaluated through hash table techniques, with the result that the time taken is not dependent on the number of rules in the section.
•[url] sections are not allowed in <Admin> or <Forward> layers.
[url.domain]
The [url.domain] section is used to group a number of rules that test the URL domain. The [url.domain] section restricts the syntax of rules in the section. The first token on the rule line is expected to be a pattern appropriate to a url.domain= trigger. The trigger name is not included. (The [url.domain] section replaces the
•Rules in [url.domain] sections are evaluated through hash table techniques, with the result that the time taken is not dependent on the number of rules in the section.
•[url.domain] sections are not allowed in <Admin> or <Forward> layers.
[url.regex]
The [url.regex] section is used to test the URL. The [url.regex] section restricts the syntax of rules in the section. The first token on the rule line is expected to be a pattern appropriate to a url.regex= trigger. The trigger name is not included . The [url.regex] section replaces the [Regex] section used in previous versions of CPL.
•Rules in [url.regex] sections are evaluated sequentially, top to bottom. The time taken is proportional to the number of rules in the section.
•[url.regex] sections are not allowed in <Admin> or <Forward> layers.
[server_url.domain]
The [server_url.domain] section is used to test the domain of the URL used to fetch content from the origin server. The [server_url.domain] section restricts the syntax and rules in the section. The first token on the rule line is expected to be a pattern appropriate to a server_url.domain= trigger. The trigger name is not included.
[server_url.domain] sections contain policy rules very similar to [url.domain] sections except that these policy rules test the server_url, which reflects any rewrites to the request URL.
•Rules in [server_url.domain] sections are evaluated through hash table techniques, with the result that the time taken is not dependent on the number of rules in the section.
