There are many ways to redirect visitors from one domain/website to another. The so-called URL redirection is often recommended. In contrast to parking a domain name, a URL forwarding can be done only if the domain name 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 may set up email addresses or subdomains and use them. This kind of feature has many practical uses - if you decide to switch your domain address, you could forward the visitors, but the e-mail messages with the old one shall still be active whenever you are getting in touch with customers or partners. When you have 2 very similar sites and you would like to rebuild one of them, you may redirect the website visitors to the other site in order to avoid losing potential customers, while you will still be able to access the administrator area for the first website and work on it.
