from Release Notes-1.0.txt,v

Access Log Types :
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: The user forced a refresh("Reload").


Can anybody explain the TCP_IFMODSINCE type or the
If-Modified-Since GET method ?
Sometimes, when the requested object is in the cache, the squid
access.log file shows TCP_IFMODSINCE instead of TCP_HIT.
What is the difference between TCP_HIT and TCP_IFMODSINCE ?
