There are many ways to redirect 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 feasible only if the domain in question is hosted. What this means in simple terms is that you may still open any content in case you have a direct link to it and you may create email addresses or subdomains and use them. This kind of feature has several practical uses - if you decide to switch your domain, you may forward the traffic, but the emails with the old one will still be active whenever you are communicating with customers or partners. If you have 2 identical websites and you intend to rebuild one of them, you can redirect the website visitors to the other Internet site in order to prevent losing potential customers, while you'll still be able to access the administration area for the first website and improve it.
