[Bug-wget] how to discriminate virtual hosts

[Giacomo Lacava]

Hi,
I'm trying to use wget to retrieve the content of a virtual host, without
downloading anything from others even if they are behind a redirect.

This doesn't seem to be possible at the moment; even if I use -D and specify the
subdomain (e.g. www.mysite.com), redirects will be followed to other subdomains
(e.g. store.mysite.com) as long as it's on the same machine.

Do I understand correctly? 
Is there any way for the -D option to actually filter on the provided hostname
rather than on the resolved IP, not discarding the subdomain?

Best regards and thanks for all your work,
Giacomo Lacava
