This chapter includes API request for managing HTTP caching rules. The HTTP Rules engine allows users to customize the CDN edge server behavior, e.g. how the CDN will manage cache and redirection.

A CDN resource can be configured with up to 100 rules. This is collectively called a ruleset. A rule consists of conditions and actions. A condition consists of a subject, which determines the value to select, and a predicate, which specifies what to compare the subject against. Conditions are bonded by the connectives “AND” or “OR”. When all the conditions are met, the CDN edge server will perform the actions associated with the rule.
