Thanks for working with me on this.  First of all about the spec.  It seems to
say that caching is not expected but can occur and that's why the no-cache
directive exists.  For the pages you send that should never be cached, like in
the cataloging interface and screens with a user login, if you are not explicit
some user agents will cache it and be valid doing so.  Personally I prefer this
behavior since my 33.6kbps line seems much faster.

Caching is per resource. Unless you serve your javascript, css and images
inline or through the php page adding the caching directive, they will not be
cached.  In fact, you best explicitly tell them to be cached by adding
reasonable expires headers.  But that's tough to do as the developer since you
php code is not involved in the serving of images.

I think I experienced this with firefox on windows, or maybe opera.  It was a
long time ago.  Anyway, it could happen anywhere that a proxy or client is
configured for liberal caching.
