There are many ways to redirect visitors from one domain/website to another. The so-called URL redirection is frequently preferred. In contrast to parking a domain name, a URL redirection is feasible only if the domain name in question is hosted. What this means in simple terms is that you could still open any content in case you have a direct link to it and you may set up e-mail addresses or subdomains and use them. This kind of function has many practical uses - if you decide to switch your domain name, you could redirect the traffic, but the e-mails with the old one will still be active in the event that you are making contact with customers or partners. If you have 2 similar websites and you need to rebuild one of them, you may redirect the visitors to the other website to avoid losing potential clients, while you shall still be able to access the admin area for the first site and improve it.
