There are many ways to forward traffic from one domain/website to another. The so-called URL redirection is often favored. In contrast to parking a domain name, a URL redirection is possible only if the domain in question is hosted. What this means in simple terms is that you may still open any content if you have a direct link to it and you may create email addresses or subdomains and use them. This type of function has many practical uses - if you decide to switch your domain name, you could forward the visitors, but the emails with the old one will still be active if you are making contact with customers or partners. When you have 2 similar websites and you intend to rebuild one of them, you could redirect the website visitors to the other website so that you can avoid losing potential clients, while you shall still be able to access the administration area for the first Internet site and work on it.
