There are a lot of ways to redirect website visitors from one domain/website to another. The so-called URL redirection is often favored. In contrast to parking a domain address, a URL forwarding is possible only if the domain in question is hosted. What this means essentially is that you may still open any content if you have a direct link to it and you may create e-mail addresses or subdomains and use them. This type of feature has many practical uses - if you decide to switch your domain, you may forward the site visitors, but the emails with the old one will still be active if you are communicating with clients or partners. In case you have two similar sites and you need to rebuild one of them, you could forward the traffic to the other Internet site to prevent losing potential customers, while you'll still be able to access the admin area for the first website and work on it.
