There are many ways to forward traffic from one domain/website to another. The so-called URL redirection is frequently recommended. In contrast to parking a domain, a URL forwarding can be done only if the domain in question is hosted. What this means basically is that you may still open any content in case you have a direct link to it and you can create email addresses or subdomains and use them. This type of function has many practical uses - if you choose to switch your domain, you could redirect the traffic, but the emails with the old one shall still be active whenever you are getting in touch with customers or partners. If you have two similar sites and you need to rebuild one of them, you can redirect the site visitors to the other Internet site so as to avoid losing potential customers, while you will still be able to access the admin area for the first Internet site and develop it.
