The invention is directed to techniques, in a caching device, for
providing content, comprising the steps of obtaining content from an
origin server, observing an access identifier provided by the origin
server in response to a first content request, the access identifier
providing an authentication indication for accessing the content obtained
from the origin server, receiving a second content request, and one of
(i) preventing the origin server from handling the second content request
and providing the obtained content when the second content request
includes the access identifier, and (ii) forwarding the second content
request to the origin server for processing when the second content
request does not include the access identifier.
