There are a lot of ways to redirect traffic from one domain/website to another. The so-called URL redirection is often favored. In contrast to parking a domain name, a URL forwarding is possible 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 can set up e mail addresses or subdomains and use them. This kind of feature has lots of 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 communicating with customers or partners. In case you have 2 very similar Internet sites and you intend to rebuild one of them, you can forward the traffic to the other website to prevent losing potential customers, while you shall still be able to access the admin area for the first website and improve it.
