There are many ways to forward site visitors from one domain/website to another. The so-called URL redirection is frequently preferred. In contrast to parking a domain address, a URL redirection is feasible only if the domain in question is hosted. What this means basically is that you can 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 kind of feature has lots of practical uses - if you decide to switch your domain, you may forward the site visitors, but the e-mails with the old one shall still be active whenever you are communicating with customers or partners. In case you have two identical sites and you would like to rebuild one of them, you could redirect the traffic to the other Internet site in order to avoid losing potential clients, while you will still be able to access the admin area for the first website and improve it.
