There are various ways to redirect visitors from one domain/website to another. The so-called URL redirection is often preferred. In contrast to parking a domain, a URL forwarding can be done only if the domain name in question is hosted. What this means essentially is that you can still open any content if you have a direct link to it and you may create e mail addresses or subdomains and use them. Such a function has several practical uses - if you decide to switch your domain address, you may forward the traffic, but the emails with the old one will still be active if you are getting in touch with clients or partners. When you have 2 very similar Internet sites and you need to rebuild one of them, you may redirect the visitors to the other Internet site to avoid losing potential clients, while you'll still be able to access the administrator area for the first website and improve it.
