hello

I organize a set of domains looking like

Main domain :http://guide-nautique.org/

sub domain:
<http://provence.guide-nautique.org/>
<http://corse.guide-nautique.org/>
<http://italie.guide-nautique.org/>
etc...

I would like to download all of them linked together

I try both two options

keep on the same TLD but there is a alot of foreign links
and I try too keep on the same domain but I download only the main domain and
not he subdomains 

Thanks a lot
