There are many ways to forward visitors from one domain/website to another. The so-called URL redirection is commonly favored. In contrast to parking a domain, a URL forwarding is possible 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 could create e-mail addresses or subdomains and use them. This sort of function has lots of practical uses - if you choose to switch your domain address, you may forward the site visitors, but the e-mails with the old one shall still be active in the event that you are making contact with customers or partners. When you have 2 identical websites 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 clients, while you will still be able to access the administration area for the first website and develop it.
