There are many ways to forward traffic from one domain/website to another. The so-called URL redirection is often preferred. In contrast to parking a domain, 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 if you have a direct link to it and you may set up e-mail addresses or subdomains and use them. This type of function has many practical uses - if you choose to switch your domain name, you could forward the site visitors, but the e-mail messages with the old one shall still be active in the event that you are getting in touch with customers or partners. In case you have 2 very similar Internet sites and you intend to rebuild one of them, you may redirect the website visitors to the other site in order to prevent losing potential customers, while you shall still be able to access the admin area for the first website and work on it.
