We recently eliminated the TCP_IMS_MISS log type.

When the client request includes an IMS.....

If its NOT in our cache, its logged as TCP_MISS. The HTTP status
code indictates 304, or 200, or whatever.

If it is in our cache, and it is expired, we forward the request
to the origin server. It is logged as LOG_TCP_REFRESH_MISS.
The HTTP status code indictates 304, or 200, or whatever

If it is in our cache, and it is not expired, Squid returns
either 304 or 200 and logs it with TCP_IMS_HIT.
