The final url used to do the put will have the container name and the
object name.

For e.g https://swift-cluster.example.com/v1/AUTH_a422b2-91f3-2f46-74b7-d7c9e8958f5d30/container/object?temp_url_sig=da39a3ee5e6b4b0d3255bfef95601890afd80709&temp_url_expires=1323479485

In the case above, "container" is the container name and "object" is
the object name. The Swift cluster will compute the signature based on
these. It will match the signature it computes with the one sent via
the temp_url_sig parameter. If they don't match, the request will be
rejected.
