There are a number of ways to forward site visitors from one domain/website to another. The so-called URL redirection is often recommended. In contrast to parking a domain address, a URL redirection is feasible only if the domain in question is hosted. What this means essentially is that you can still open any content in case you have a direct link to it and you could set up e mail addresses or subdomains and use them. Such a feature has many practical uses - if you decide to switch your domain address, you can forward the traffic, but the e-mails with the old one shall still be active if you are communicating with clients or partners. In case you have two identical sites and you need to rebuild one of them, you can forward the website visitors to the other website to prevent losing potential customers, while you'll still be able to access the administration area for the first site and develop it.
