I have much clear concepts now, thanks.

My remaining problem is related to those files which do not have
expire set from backend (only LM begin set)

1. I found that if a file only has LM being sent out, the browser
seems to cache the file forever and won't request the server until you
press F5, is it true?

2. Squid will not cache for a file if expire has not been set, is it true?

3. The prioiry of client sending cache-control, max-age=0 is higher
than IMS and must force contacting the backend to refresh (i.e. not
304 but 200).

Thanks again.
