- TCP_MISS/200 means that the requested document was not in the cache but it could fetch it OK from the web server. The direct at the end says that the file was fetched from the webserver.
- TCP_IMS_HIT/304 means that the client asked if the file has changed, and squid checked its date/time on the webserver and found it had not changed, so it gave a copy of the file to the client out of its local cache.
