I'm getting several of these in my access.log:


From the ChangeLog:

        - Added more IMS support. Now Squid issues IMS requests for
          expired objects in the cache. Log type will be either
          TCP_EXPIRED_HIT if the server sends "304 Not Modified" or
          TCP_EXPIRED_MISS if the server send a new object.

Surely then, if the server sent a new object the reply code sent back to
the client would be 200, not 304.

Could it be that the client has a newer copy of the page than Squid, so
Squid only sends a 304 to the client but keeps the updated content? If
that's the case, how can I find out the size of the new page - on all
TCP_EXPIRED_MISS/304 lines, the size is less than 100 bytes (presumably the
size of a 304 response).

Please clear my confusion...
