bool http_cache_etag

] )
Attempts to cache the sent entity by its ETag, either supplied or generated by the hash algorithm specified by the INI-опцию http.etag.mode. If the clients If-None-Match header matches the supplied/calculated ETag, the body is considered cached on the clients side and a 304 Not Modified status code is issued. A log entry is written to the cache log if the INI-опцию http.log.cache is set and the cache attempt was successful.
If this function is used outside the http_send_*() API, it facilitates the ob_etaghandler(). Список параметров
