There are a lot of ways to forward website visitors from one domain/website to another. The so-called URL redirection is frequently recommended. In contrast to parking a domain name, a URL forwarding can be done only if the domain name in question is hosted. What this means basically is that you may still open any content if you have a direct link to it and you can set up email addresses or subdomains and use them. This type of feature has many practical uses - if you decide to switch your domain name, you may redirect the visitors, but the emails with the old one shall still be active in case you are communicating with clients or partners. If you have 2 identical sites and you need to rebuild one of them, you could forward the visitors to the other site so as to prevent losing potential customers, while you'll still be able to access the administration area for the first Internet site and develop it.
