There are many ways to forward visitors from one domain/website to another. The so-called URL redirection is often preferred. In contrast to parking a domain address, a URL redirection can be done only if the domain name in question is hosted. What this means basically is that you can still open any content if you have a direct link to it and you could create email addresses or subdomains and use them. This type of feature has lots of practical uses - if you want to switch your domain name, you could forward the visitors, but the e-mails with the old one shall still be active if you are making contact with clients or partners. If you have 2 very similar sites and you would like to rebuild one of them, you may forward the traffic to the other website to prevent losing potential customers, while you will still be able to access the admin area for the first Internet site and develop it.
