in all technical, you can already do this.. the only issue is that it require running another HFS execution...
You will have to go in to the HFS menu and make sure that the "only 1 instance" is not checked...
I've found that if you start in C:\HFS PAth\ and add HFS1 Make a HFS and Save the VItural Files system, then copy that folder and a new folder in the same path lets say HFS2
, then load the file system and make changes... you now have 2 HFS exe to run a vitural file system... ITs not a praticale as opening a confi like in apache, but is accomplishable!...
Example:
c:\webroot\hfs1\hfs.exe -running site name.com:80
and
C:\webroot\hfs2\hfs.exe -runnin site name.com:8080
both HFS exe will be runnin at the same time... different save to xxx.VFS
