Hi,

Can someone show how to calculate the age here? Is it
age=Now-LM or age=time since the object stored in the
cache?
Age = time in seconds since value of Date: header received
with the Object.
Date: header in future are cropped to NOW.

Thanks, Amos.
I am confused when I read this thread http://www.squid-cache.org/mail-archive/squid-users/200710/0680.html
I think the max still can be used even the response has no LM header. Can you clarify?
No, I don't know whats going on inside your head so I can't explain what
you are thinking of.
Yes, The answer that came out does match the algorithm you are talking
about.
What if the response Date header is one day behind NOW? Is the response 1 day one by the time it reach the Cache?
Yes. Exactly. Date: is supposedly when the object was last sent from
the web server.
If its already saying 1 day old, then the object is supposedly 1 day old
and should be treated as such during the calculation.
