HTTP Cache-Control: what is acceptable default behavior when it is missing?

Question

I am facing some HTTP caching issues caused by some downstream applications without putting Cache-Control headers on time sensitive data. I need to make this a broken situation.

Is there a concise expression available on the Internet about valid or common response behavior for caches and agents when the Cache-Control header is missing for HTTP 1.1? I see RFC2616, but does not seem to contain any regulatory or NEXT statements about responses without a Cache-Control header.
