There are a number of ways to forward website visitors from one domain/website to another. The so-called URL redirection is oftentimes preferred. In contrast to parking a domain, a URL forwarding is possible only if the domain name in question is hosted. What this means basically is that you could still open any content in case you have a direct link to it and you could set up email addresses or subdomains and use them. This kind of feature has several practical uses - if you want to switch your domain name, you could redirect the site visitors, but the emails with the old one shall still be active whenever you are making contact with customers or partners. When you have two identical websites and you need to rebuild one of them, you may redirect the site visitors to the other website so that you can avoid losing potential customers, while you'll still be able to access the admin area for the first site and develop it.
