There are a lot of ways to redirect traffic from one domain/website to another. The so-called URL redirection is commonly preferred. In contrast to parking a domain address, a URL forwarding is feasible only if the domain name in question is hosted. What this means in simple terms is that you can still open any content if you have a direct link to it and you could set up email addresses or subdomains and use them. Such a function has numerous practical uses - if you choose to switch your domain, you may forward the visitors, but the emails with the old one will still be active whenever you are making contact with customers or partners. In case you have 2 identical sites and you need to rebuild one of them, you could forward the website visitors to the other site in order to prevent losing potential clients, while you'll still be able to access the administration area for the first website and work on it.
