This step-by-step article shows you how to use Host Headers to allow multiple host names to share a single IP address.
IIS allows you to assign any number of sites to a single IP address and distinguish them by using host headers. When IIS receives a request for a Web page, it looks at the information sent in by the browser. If the browser is HTTP 1.1 compliant (Internet Explorer 3.x and later, or Netscape Navigator 3.x and later), the HTTP header contains the actual domain name requested. IIS uses this to determine which site should answer the request.
If the browser is not HTTP 1.1 compliant, you can program a core page to display all sites available and allow the user to choose which site to use. For instructions on how to do this, see the references section at the bottom of this article.
