Yep that's right - the 'Pragma: no-cache' that curl send by default will
instruct any caches along the way to retrieve a fresh copy of the object.
(It's of course possible for caches to disregard this request - often
caches are set up that way to over-ride the gratuitous use of no-caches on
ad-servers).

Some caches add headers to the response to the client to indicate they've
touched the request, this information can also include whther or not the
request was retrieved from the cache or not.

Cheerio,
