Rather than suffering by experimentation, I'd ask and hear if anybody has attempted this before. How do I deploy our Mendix app as a Virtual Folder in IIS, on an existing website, so that everything Mendix needs will be found under http://domain/virtualfolder, for example the mxclientsystem now lives under http://www.domain.com/virtualfolder/mxclientsystem instead of http://www.domain.com/mxclientsystem
