Web server directories and URLs
When IIS is installed, it creates a directory for the default Web site on that machine.  The default directory is:
   c:\inetpub\wwwroot\
The URL of your default Web site is simply:
   http:///
or
   http:///
If you are a Web developer, you will test your site using the server on your own machine:
   http://localhost/
Your Web site may have a number of sub-directories.  For example, if you have a sub-directory called som on your development machine:
   c:\inetpub\wwwroot\som\
it's URL would be:
   http://localhost/som/
You can also create a virtual Web site which points to a sub-directory, but has a different name and perhaps different properties than the real Web site for that sub-directory.  For example, the URL:
   http://localhost/hoho/
refers to a virtual site called hoho even though there is not a directory called
   c:\inetpub\wwwroot\hoho\
on my computer.
