Pulp

When trying to download from the wrong location, i'd expect the content app to serve a 404 response. Instead, it simply closes the connection.

In the test log i see:

requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',))

And pjournal shows:
