 // [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.
