There are various ways to forward traffic from one domain/website to another. The so-called URL redirection is oftentimes favored. In contrast to parking a domain name, a URL redirection is possible only if the domain in question is hosted. What this means basically is that you could still open any content if you have a direct link to it and you may set up email addresses or subdomains and use them. Such a function has many practical uses - if you decide to switch your domain address, you may forward the site visitors, but the e-mails with the old one shall still be active if you are getting in touch with customers or partners. In case you have two very similar websites and you intend to rebuild one of them, you could forward the 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 develop it.
