There are many ways to forward visitors from one domain/website to another. The so-called URL redirection is often preferred. 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 in case you have a direct link to it and you may set up e-mail addresses or subdomains and use them. This kind of feature has numerous practical uses - if you decide to switch your domain, you can redirect the site visitors, but the e-mail messages with the old one shall still be active whenever you are getting in touch with customers or partners. If you have 2 very similar sites and you would like to rebuild one of them, you may forward the website visitors to the other Internet site so as to prevent losing potential clients, while you'll still be able to access the administrator area for the first site and work on it.
