As promised I have tested out a couple of more browsers. See below for
my results

Browser PUBLIC.PHP3 PRIVATE.PHP3 NOCACHE.PHP3
---------- --------- --------- -----------
Opera 3.6
Win95 cached cached cached!!!

Netscape 4.7
Win95 cached not cached not cached

Take a look at http://www.mnot.net/cacheability/ for a cacheability
tester and a good write-up on cache issues and options.

I don't know where Opera is coming from. It is not only non-HTTP 1.1
aware (this is expected since this version was released a while ago),
but doesn't even seem to use the fallback HTTP 1.0 headers of Expire
and Pragma. I have had problems with Opera caching before and have
reported them to Opera in the past - it seems like the problem has
still not been fixed. I am not sure there is any set of headers that
can make Opera not cache a page.

Summary so far....
--------------------
Opera appears to be hopeless with respect to controlling the cache
properly.

NS 4.x doesn't support HTTP 1.1 cache-control and therefore falls back
to HTTP 1.0 Expires. Threfore NS caching is properly controlled by the
latest CVS session.inc.

MSIE 5.x supports HTTP 1.1 cache-control. Therefore MSIE 5.x caching
is properly controlled by the latest CVS session.inc
-------------------

Anyone else test their browsers against http://renaghan.com/cache/ ??
Let us know.
I am very interested in a Mozilla 5 beta, and an MSIE 4.x test.
