There are many ways to forward site visitors from one domain/website to another. The so-called URL redirection is oftentimes favored. In contrast to parking a domain name, a URL redirection can be done only if the domain name in question is hosted. What this means basically is that you could still open any content if you have a direct link to it and you could set up e-mail addresses or subdomains and use them. This kind of feature has many practical uses - if you want to switch your domain address, you can forward the site visitors, but the e-mails with the old one shall still be active in case you are getting in touch with clients or partners. If you have 2 identical sites and you would like to rebuild one of them, you could redirect the website visitors to the other Internet site so that you can avoid losing potential clients, while you'll still be able to access the administrator area for the first site and develop it.
