1) Suppose that you want your web server to present a collection of documents called doc1.html and doc2.html. They are located in the systemroot\home\sales\docs directory.
2) Make this folder accessible to users under the URL https://www.anycompany.com/sales/doc1.html.
3) If you do not make these folders accessible, the web servers would attempt to satisfy the web browser's request by looking for the directory \Inetpub\wwwroot\sales\docs\.
4) Using a virtual directory solution, the doc1.html and doc2.html files reside in the systemroot\home\sales\docs directory and are accessed by www.yoursite/sales/docs1.html
5) Using a virtual directory solution, the doc1.html and doc2.html files now reside in the systemroot\home\sales\docs directory and are accessed by the same URL
