There are many ways to redirect traffic from one domain/website to another. The so-called URL redirection is oftentimes favored. In contrast to parking a domain name, a URL redirection is feasible only if the domain in question is hosted. What this means essentially is that you may still open any content if you have a direct link to it and you could set up e-mail addresses or subdomains and use them. This sort of feature has many practical uses - if you choose to switch your domain address, you may redirect the visitors, but the e-mail messages with the old one will still be active in case you are making contact with customers or partners. When you have 2 identical websites and you need to rebuild one of them, you could redirect the visitors to the other site so as to avoid losing potential clients, while you will still be able to access the admin area for the first site and improve it.
