mirror sites

[Yvonne Reynolds]

Hi,
I hope someone can help.. we are considering setting up a mirror site  - something I know very little about  

technically what is involved here?  
Does one have to register a separate domain name for the mirror site.  Or do you just list a separate set of DNS (our site has a set of 2 DNS currently) under the same domain name and this second set serves the mirror site?   I am sure it must be a bit more complicated than this.


Does anyone know of a good internet reference on setting up mirror sites?

thanks in advance.
Yvonne
