Is not the worst... but near.
They are in different locations but running the same OSes: Unix, Apache.
The main idea is to offer some people the service to create web pages using my script in my "Server 1" but allowing them to own is domain: www.hisdomain.com with his own server...and the generated web pages, and not (like now) www.mydomain.com/somepeople.
Anyway I thank you very much. I will investigate WebDAV.
