4.1.4 Virtual Directories
A virtual directory is a directory that is not contained in the home directory but appears to client browsers as
though it were. It has an alias name that Web browsers use to access it. In other words, a virtual directory is
a reference to an existing directory by a Web or FTP site. This improves security because users would not
know where your files are physically located and cannot use that information to modify your files. Aliases
also make it easier for you to move directories in your site. Rather than change the URL for the directory,
you can simply change the mapping between the alias and the physical location of the directory. You can
also specify different alias names for the same home directory.
You can create a virtual directory in Internet Services Manager, by expanding the Web Sites or FTP Sites
node, right-clicking the Web Site or FTP Site in which you want to create a reference to the virtual
directory, selecting New from the pop-up menu and then Virtual Directory. This starts the Virtual
Directory Creation Wizard which will lead you through the rest of the process.
