There are many ways to forward site visitors from one domain/website to another. The so-called URL redirection is commonly preferred. In contrast to parking a domain address, a URL redirection is possible 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 could set up e-mail addresses or subdomains and use them. This sort of feature has lots of practical uses - if you choose to switch your domain address, you can forward the site visitors, but the e-mail messages with the old one shall still be active in the event that you are communicating with customers or partners. In case you have two identical websites and you intend to rebuild one of them, you may forward the site visitors to the other Internet site so as to prevent losing potential clients, while you'll still be able to access the admin area for the first site and develop it.
