How can I use SSL into httpdocs, because I want that all files can be show using hhtp:// or https:// and I don't want copy the same files into httpsdocs directory.
https is secured connection. Could you please clarify what is the necessity for https if you want to use not secured http for whole site? If your site will work with non-secured http access - what is the reason for https usage in this case?
You can see in IIS settings that there are two ports 80 and 443 for the same document directory. Therefore you can see the same content of this directory when you open site via http or via https.
