HIS calls LoadLibray for your ISAPI DLL (in this example, DilStub.dll) DllStub.df! Contains forward reference to SomeFunc In DhlWork.dil due to this line of code in DllStub.cte #pragma comment ( linker, "/ export:SomeFunc=dllwork.SomeFunc") When DllStub.dll loads, DllWork loads implicitly because of forward function reference DllWork dhl DilWork contains the actual implementation of SomeFunc.
