<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">When you have a remote metadata source expire on you, often you get very little in the logs around this because of some interactions between the logging and caching.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">We currently log the "nothing's changed" message on DEBUG, which I'm inclined to bump to INFO. Normal use you wouldn't see that much additional noise, just one message per attempt and it helps clarify what the subsequent "attempted refresh" message refers to.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The expiration problem is hard. Since the metadata hasn't changed, the resolver never actually loads a copy of the file that's "pre-expired" or even headed toward expiring, which is the one time we really log something about it. So it basically never changes, never reloads, and silently expires in the cache.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">Once the aggregate is loaded, we sort of lose the notion of it as an object with its own expiration so there's no easy way to track it or report it out to the status page. I suppose we could report out the validity of the root element at the time it loads via status or metric.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I was thinking maybe an overall improvement would be to have an option to cap the length of time the cache control tag is held. If it could be flushed daily, that would force a reload at least every so often, and give the system a chance to see a violation of, say, the ValidUntil filter.</p>
