Okay. I think I'm getting a better handle on this now. Thanks for
One more question regarding conditional requests:
What happens when a client sends a conditional request (either INM or
IMS) and the content is not available in the Varnish cache? I assume
that Varnish will just relay the original conditional request through
to the backend. But then what happens when the backend responds with
a 304? I'm guessing Varnish won't cache a response until a non-304
is returned. Correct?
