There are a lot of ways to forward visitors from one domain/website to another. The so-called URL redirection is commonly favored. In contrast to parking a domain address, a URL redirection is feasible 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 could create email addresses or subdomains and use them. This kind of feature has several practical uses - if you choose to switch your domain, you could redirect the site visitors, but the e-mail messages with the old one shall still be active in case you are communicating with customers or partners. If you have 2 very similar sites and you need to rebuild one of them, you may forward the website visitors to the other site to avoid losing potential clients, while you'll still be able to access the administrator area for the first Internet site and develop it.
