Sure!
I've found that Microsoft devices honor this option, but others do not.
I would be in support of something similar to provide this support, but =
the part of my original reply you missed is that the content is =
deliberately not-cachable on the part of either the CDN or the =
originator. Microsoft patches are also not easily cacheable as well =
because they only request about 100Kb per request, so you get an awful =
lot of HTTP/206.
They also make it easier to run local caches for an enterprise.
The apple process requires the full patch to come down in one-shot and =
doesn't like being interrupted.
It might be easier for Warren to ship each customer a 16GB USB with the =

to know how to use them.... I know what to do, but my other family =
members, not so much...
