CI Episode-3 Creating Virual Host for your website

Running a Web server on your desktop computer is a great way to speed up Web site development. By previewing your Web pages directly through a Web server on your own computer you can test out server-side programming like server-side include files, form processing scripts, or database-driven Web pages. However, there’s one problem associated with running a server on your own computer: by default, you only have a single "domain"–http://localhost/–so if you work on more than one Web site you put them all under "localhost" in different directories. This isn’t very real world and can cause problems when using server-side includes and root-relative links. Fortunately there’s a better way.
