John,
I think WWC can work as a VFP mtdll, but, from everything I've read on it and seen, it's strongly advised that it not be used that way. I would estimate from 0 to less than 1% use it this way, but, I'm open to be corrected on this. The primary way WWC works is in 1 of 2 ways both using multiple .vfp. .EXE backends. The first uses a 'file-based' method which communicates with the .EXE backends by passing small text files from the web server(performance will suffer greatly on busy sites using this method). The second method uses COM to communicate between the web server and the .EXE backends(this is the preferred and more scalable method).DCOM must be used to set up the .VFP. .EXE COM servers...

>>I believe the difference is that WWC uses DCOM and .EXEs and I think he's looking for the MS presribed way to do web apps with .vfp. which is with .vfp. Multi-threaded .dlls (mtdlls) which can be called from ASP, ASP.NET and web services.
