Earlier in the thread, you show how to use curl to GET the metadata.
So the cron job dictates when the file is refreshed regardless of
whether or not the file has changed. OTOH, Shibboleth (both SP and
IdP) will skip a refresh attempt if the file has not changed.

I wouldn't be surprised if a lot of SPs were doing this now but I
would be surprised if I found out the same were true for IdP
deployments. May I ask what makes you think this is so?

Perhaps you're right but this is still cause for concern. The fact
that we're even having this discussion is cause for concern.

I'm aware of the SP issue but not the IdP issue. Can you provide a
pointer (or an explanation)?

Thanks,
