1. A system configured for managing traffic on a digital content delivery network [ system of distributed network servers] , the system comprising:
one or more hardware processors configured by machine-readable instructions to:
receive an item of digital content on a digital content delivery network [ system of distributed network servers] ;
assign a type category to the item of digital content;
determine an update time variable of the item of digital content;
determine a cache time for the item of digital content based on the type category of the item of digital content and the update time variable of the item of digital content, wherein the step of determining a cache time comprises applying a rule to determine the cache time, wherein the rule includes multiple time periods that are each respectively associated with a corresponding update time variable and wherein a time period is selected as the cache time based on the time period corresponding to the update time variable of the item of digital content, wherein the rule further includes type categories each having a corresponding offset and the step of determining the cache time further comprises multiplying the selected time period by the offset corresponding to the type category of the item of digital content; and
cause an instance of the item of digital content to be cached in a cache memory associated with the content delivery network [ system of distributed network servers ] for the cache time and allowing removal of the instance of the item of digital content from the cache memory after the cache time has lapsed.
