There are various ways to redirect website visitors from one domain/website to another. The so-called URL redirection is commonly recommended. In contrast to parking a domain address, a URL forwarding is feasible only if the domain 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 create email addresses or subdomains and use them. Such a function has many practical uses - if you decide to switch your domain address, you may forward the visitors, but the emails with the old one shall still be active in case you are making contact with customers or partners. If you have two identical Internet sites and you need to rebuild one of them, you could redirect the website visitors to the other Internet site to avoid losing potential customers, while you shall still be able to access the admin area for the first site and develop it.
