There are a number of ways to redirect site visitors from one domain/website to another. The so-called URL redirection is often recommended. In contrast to parking a domain name, a URL redirection is possible only if the domain in question is hosted. What this means essentially is that you could still open any content in case you have a direct link to it and you may create email addresses or subdomains and use them. Such a feature has lots of practical uses - if you decide to switch your domain address, you can forward the visitors, but the e-mails with the old one shall still be active whenever you are getting in touch with customers or partners. If you have 2 very similar Internet sites and you need to rebuild one of them, you can forward the visitors to the other website so as to prevent losing potential clients, while you'll still be able to access the administration area for the first website and work on it.
