Has anybody used Polygraph with Netscape Proxy? Were you able to get hits?

It is not mandatory. However, if proxy time is different from server time,
it may not cache any responses because they would appear to be generated
"in the future". It all depends on the caching policy that Netscape is
using, and I do not know what that policy is.

What you need to do is to wait till Polygraph complains about the first
false miss and then go back in trace and find the other request(s) for the
same object. After that, you just apply your knowledge of HTTP and common
sense to decide whether the object should have been cached.

The problem you experience is not related to filling the cache. Polygraph
does not reuse the objects from the fill.
BTW, can you get hits from that proxy when you revisit real Web pages?
P.S. Your message did not contain any attachments as far as I can tell.
Your mailer is probably stripping all attached documents.
