There are a number of ways to redirect visitors from one domain/website to another. The so-called URL redirection is frequently preferred. In contrast to parking a domain name, a URL forwarding is possible only if the domain name 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 e-mail addresses or subdomains and use them. This type of function has many practical uses - if you want to switch your domain, you can redirect the site visitors, but the emails with the old one shall still be active in the event that you are communicating with customers or partners. When you have two identical Internet sites and you need to rebuild one of them, you could redirect the visitors to the other site in order to prevent losing potential clients, while you'll still be able to access the administration area for the first site and improve it.
