Users might already have the file cached. If website-a.com links to [link] , and a user goes from there to website-b.com who also links to [link] , then the user will already have that file in their cache. On a slower, higher-latency connection, the story is much, mush worse. Penalty: Caching. Myth: Cross-Domain Caching.
