This is a broad question about both the 2.0 IdP and the 2.0 SP.

With 1.3, we all made cron jobs to go fetch and verify metadata 
periodically.  In 2.0, both the IdP and SP support performing periodic 
fetch and verify themselves, along with cacheing a local copy.  This is 
all good.

My question is whether the new code always fetches the full file, or 
whether they try and optimise bandwidth by not fetching the body if the 
file hasn't changed since the last fetch?

Obviously if the new code did do this, we might be more sanguine about 
telling people to poll more frequently.

P.S. I don't think that you'd need to preserve "last fetch time" over a 
restart; it would be perfectly fine for the code to always fetch when it 
was restarted.
