-// PREF: Race Cache With Network (RCWN) [FF59+] [REMOVED FF152+]
-// [ABOUT] about:networking#rcwn
-// Firefox concurrently sends requests for cached resources to both the
-// local disk cache and the network server. The browser uses whichever
-// result arrives first and cancels the other request. This approach sometimes
-// loads pages faster because the network can be quicker than accessing the cache
-// on a hard drive. When RCWN is enabled, the request might be served from
-// the server even if you have valid entry in the cache. Set to false if your
-// intention is to increase cache usage and reduce network usage.

 // PREF: cache memory pool
 // Cache v2 provides a memory pool that stores metadata (such as response headers)
 // for recently read cache entries [1]. It is managed by a cache thread, and caches with
 // metadata in the pool appear to be reused immediately.
