'wc.dll' is a commercial product from West-Wind.
It is a simple ISAPI connector in a C++ DLL to connect IIS to a VFP program (passed as a parameter, generally in the URL).

It is one of the solutions available to VFP developers to run VFP code in the web. There are also other companies that allow you to run in the web as you see in this thread.
