There are a lot of ways to redirect traffic from one domain/website to another. The so-called URL redirection is commonly preferred. In contrast to parking a domain name, a URL forwarding is feasible only if the domain in question is hosted. What this means essentially is that you can still open any content in case you have a direct link to it and you could set up email addresses or subdomains and use them. Such a feature has many practical uses - if you want to switch your domain address, you may forward the visitors, but the e-mails with the old one will still be active in case you are making contact with clients or partners. In case you have 2 similar websites and you would like to rebuild one of them, you can redirect the traffic to the other site in order to avoid losing potential clients, while you'll still be able to access the administration area for the first Internet site and improve it.
