There are a lot of ways to redirect site visitors from one domain/website to another. The so-called URL redirection is commonly preferred. In contrast to parking a domain name, a URL redirection can be done only if the domain in question is hosted. What this means in simple terms is that you could still open any content in case you have a direct link to it and you can set up e-mail addresses or subdomains and use them. This kind of feature has many practical uses - if you want to switch your domain, you can forward the traffic, but the e-mail messages with the old one will still be active in case you are communicating with clients or partners. When you have two identical sites and you would like to rebuild one of them, you could redirect the site visitors to the other site to prevent losing potential customers, while you shall still be able to access the admin area for the first Internet site and improve it.
