   You can't set a virtual path with the Host header, it is not valid if you want to follow the RFC.
   After as well, you can include the port in it, but I think you are not sure if you can't really know
   if you should create https URL or not, you don't have this information (this is not required
   only to be on port 443, and if it is I am not even sure the port is correctly added in the Host
   header).

   I think it would be safer to have a separate header for all this information, and not touching
   the Host headers, that applications might expect to be correct.
