Having worked with setups creating this problem all in all it's possible
variants. Here follows a breakdown of what is causing bogus
[Content-]Location headers:

Bad host name: Server configured with a bad server name and not
reflecting the Host header back in generated URLs.

Bad port: Some device in front of the server remaps the request port
(i.e. NAT) without the server being aware or capable of handling the
situation.

Bad absolute path, bad protocol, or any of the above: A reverse proxy
remapping requests in the URL-namespace without properly undoing the
mappings in returned [Content-]Location headers.

Henrik
