There are various ways to redirect traffic from one domain/website to another. The so-called URL redirection is frequently favored. In contrast to parking a domain, a URL forwarding can be done only if the domain in question is hosted. What this means essentially is that you could still open any content in case you have a direct link to it and you can set up email addresses or subdomains and use them. This sort of feature has lots of practical uses - if you want to switch your domain name, you could forward the visitors, but the e-mails with the old one shall still be active in case you are communicating with customers or partners. When you have 2 identical sites and you intend to rebuild one of them, you could forward the visitors to the other Internet site so that you can prevent losing potential clients, while you will still be able to access the administrator area for the first website and work on it.
