If MaxCDN does not have any cached state for the file, which obviously
will be the case for new versions, it will first have to check the
origin mirror. This might take a while, although I never encountered
such a long delay. It probably also depends from which "edge location"
the CDN serves you and their peering.

The annoyance of unnecessarily hitting lots of mirrors is exactly what
made me add this flag. :-)
