What I did was I set http header "Cache-Control: public"
and also "Cache-Control: public, no-cache" (because of this tut:
http://www.mnot.net/cache_docs/)

But both have no effect. My Squid logfile tells me, that the PDF is not
saved on disk

But, after I removed the HTTP Basic authentifaction stuff it works and Squid saves a PDF on my disk

</snip>

So, why do I need to *store* some documents like a PDF:

We're sending lot's of emails that contain a (protected) link to
a document like a PDF. But Squid should only *load* the PDF on the first
request and save it after that to its cache store.

For the next request Squid should ask (for the same PDF) only
IF-NONE-MATCH to the web server and if PDF is the same (what it really is)
web server sends "304" back. Now Squid should use its PDF file and send it
back to the other client with "200". since that client has that PDF not in its
local cache.

Are there any hints on that issue?

Thanks a lot.

Regards,
Matthias
