There are a number of ways to redirect traffic from one domain/website to another. The so-called URL redirection is oftentimes favored. In contrast to parking a domain address, a URL redirection is possible only if the domain name 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 type of function has lots of practical uses - if you choose to switch your domain, you can forward the traffic, but the e-mails with the old one shall still be active in case you are making contact with clients or partners. When you have 2 identical websites and you intend to rebuild one of them, you could forward the website visitors to the other website to prevent losing potential customers, while you shall still be able to access the admin area for the first Internet site and develop it.
