I have CF7 enterprise and win2003 server sp1

I wish to get following configuration:
[url]https://secure.domain.com/my_cf7_instance1/hello.cfm[/url] and

I was able to create a new instance - that works fine
but now I want to create more instances of CF7 - for each directory
(my_cf7_instance1, my_cf7_instance2) a new instance of CF7 ? but still one ip /
ssl certificate

I checked [url]http://livedocs.macromedia.com/coldfusion/7/htmldocs/00001772.htm[/url]
but I'm was not able to implement that
