TCP_HIT A valid copy of the requested object was in the cache. TCP_MISS The requested object was not in the cache. TCP_REFRESH_HIT The requested object was cached but STALE. The IMS query for the object resulted in “304 not modified”. TCP_REF_FAIL_HIT The requested object was cached but STALE. The IMS query failed and the stale object was delivered. TCP_REFRESH_MISS The requested object was cached but STALE. The IMS query returned the new content. TCP_CLIENT_REFRESH_MISS The client issued a “no-cache” pragma, or some analogous cache control command along with the request. Thus, the cache has to refetch the object. TCP_IMS_HIT The client issued an IMS request for an object which was in the cache and fresh. TCP_SWAPFAIL_MISS The object was believed to be in the cache, but could not be accessed. TCP_NEGATIVE_HIT Request for a negatively cached object, e.g. “404 not found”, for which the cache believes to know that it is inaccessible. Also refer to the explainations for negative_ttl in your squid.conf file. TCP_MEM_HIT A valid copy of the requested object was in the cache and it was in memory, thus avoiding disk accesses. TCP_DENIED Access was denied for this request. TCP_OFFLINE_HIT The requested object was retrieved from the cache during offline mode. The offline mode never validates any object, see offline_mode in squid.conf file. UDP_HIT A valid copy of the requested object was in the cache. UDP_MISS The requested object is not in this cache. UDP_DENIED Access was denied for this request. UDP_INVALID An invalid request was received. UDP_MISS_NOFETCH During “-Y” startup, or during frequent failures, a cache in hit only mode will return either UDP_HIT or this code. Neighbours will thus only fetch hits. NONE Seen with errors and cachemgr requests. The following codes are no longer available in Squid-2: ERR_* Errors are now contained in the status code. TCP_CLIENT_REFRESH See: TCP_CLIENT_REFRESH_MISS. TCP_SWAPFAIL See: TCP_SWAPFAIL_MISS. TCP_IMS_MISS Deleted, TCP_IMS_HIT used instead. UDP_HIT_OBJ Hit objects are no longer available. UDP_RELOADING See: UDP_MISS_NOFETCH.
