A method to preview new cacheable content may include adding a skip-cache element to a request to preview the new cacheable content before replacing any existing content in a cache or caching the new content. The method may also include bypassing cache processing for the request in response to the request including the skip-cache element and the skip-cache element being defined in a cache policy.

Method and system to preview new cacheable content

The eviction candidate sorting tool (ECST) is used with existing eviction algorithms that utilize a database for tracking objects stored in a cache. Rather than storing all the metadata associated with an object in a cache, the ECST extracts only certain attributes from the metadata, creating an 'evict table' listing all the cached objects and the chosen attributes, or 'classes.' The table can be sorted by class based on an eviction algorithm. An eviction mechanism can use the sorted table to identify candidates for eviction.
