Maybe they are talking about 200 vs 304 caches. A browser can use be told to revalidate files, telling the server to return the content using the "If-Modified-Since" and "If-None-Match" headers. This way, the server will return 304 and empty content if the file has not changed or 200 and the file if it is new or it changed |
