There are a number of ways to forward site 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 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 can create e mail addresses or subdomains and use them. This type of function has lots of practical uses - if you want to switch your domain, you can redirect the visitors, but the e-mails with the old one will still be active in case you are communicating with clients or partners. In case you have 2 similar Internet sites and you need to rebuild one of them, you could redirect the website visitors to the other Internet site so as to avoid losing potential clients, while you'll still be able to access the admin area for the first site and improve it.
