Haven't you mistaken 304 for 200 ? the 200 means that the server is sending
the whole content to the client, while 304 means server is telling the
client that the content on client is still fresh. So with big expire time
you could expect much of 304's and little of 200's.



My understanding...

304 is used if a user conditioinally request for an object, e.g. by pressing F5.

If expire is set and still fresh, client NO need to contact my server,
so my log cannot see 304 at all...

so seeing too many 304 is abnormal...and you see my example above is
serious in IE only.


Amos: Sure even if this is IE problem, I have no way to contact them
for support... :)


Thanks.

I wonder if you have "ie_refresh on" in your configuration.
http://www.squid-cache.org/Doc/config/ie_refresh/

That will lead to some bias towards 304. The fix in that case is to get clients to upgrade their IE to more current versions.
