There are various ways to redirect visitors from one domain/website to another. The so-called URL redirection is commonly favored. In contrast to parking a domain name, a URL redirection is possible 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 may set up e mail addresses or subdomains and use them. Such a function has several practical uses - if you decide to switch your domain, you may redirect the site visitors, but the e-mails with the old one shall still be active if you are getting in touch with clients or partners. If you have two similar websites and you would like to rebuild one of them, you can redirect the traffic to the other website in order to avoid losing potential customers, while you'll still be able to access the administration area for the first website and work on it.
