There are a number of ways to forward website visitors from one domain/website to another. The so-called URL redirection is commonly favored. 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 may still open any content in case you have a direct link to it and you could create email addresses or subdomains and use them. This type of function has lots of practical uses - if you choose to switch your domain address, you can forward the traffic, but the e-mails with the old one will still be active in the event that you are communicating with customers or partners. In case you have 2 very similar websites and you would like to rebuild one of them, you could redirect the site visitors to the other website in order to avoid losing potential clients, while you'll still be able to access the administration area for the first site and improve it.
