In case you have a number of domain names with different extensions and you want all of them to open precisely the same Internet site, you can have the site under one of them and redirect all the rest. There are several ways to forward one Internet domain name to another, like the so-called domain parking. If your hosting package deal permits it, though, it'll be better if you host all of the domains and set up a URL redirect, not a domain redirect. The difference between the two is that while a domain address is hosted, you could still have content for it, create subdomains, e-mail addresses, etc., while with a parked domain it's not possible to do any of those things. As an illustration, if you're building localized sites under various country-code Internet domain names, you shall be able to work on them, but meanwhile, visitors will be redirected to the main site.
