not sure what you mean here. you mean clone a site but making it different (in a different language etc...)?
Let's say a recruitment web site with the size of Monster.com that needs to be mirrored in every country. So instead of creating a web site for every country, we simply create a web site for every language : an English web site, for instance, to be used in UK, US , Australia and Canada; a French web site for France, Belgium and Canada, etc. Cheers
the word 'mirror' implies that you want to scrape another site. this is most likely NOT allowed. if you mean make a site for multiple countries, i wouldnt. id setup individual sites for each country, not run off the same domain.
