• The browser being used does not set the Host: HTTP header. The SERVER_NAME CGI variable is set from the Host: HTTP header, but only if this is set by the browser. (Note that this header is not set by Internet Explorer 2.0.) • The IIS parameter ReturnUrlUsingHostName is not set. Set the registry parameter at W3SVC\Parameters\ReturnURLUsingHostName to allow using the fully qualified domain name of the local host. See the IIS documentation about the ReturnURLUsingHostName registry parameter.
