I moved my PHP custom web publishing on FMS16 from a Mac Server to a Windows Server. In Apache you were able to maintain multiple domain/hostnames. So I could setup a ServerName "fmdev.example.com" and make the DocumentRoot "/Library/FileMaker Server/HTTPServer/htdocs/httpsRoot/fmdev/". I can keep repeating this for each domain/hostnames. I have 4 domains. Now all of my php code throws an error and can't get it up and running.
Is there any way to mirror this behavior in IIS. I can't find any FM documentation and I am afraid to add multiple website to IIS, because FM wants port 80, 443 for itself.
