Client Code Into the Driver We use the W3C WebDriver protocol to communicate with a local instance of an HTTP server. This greatly simplifies the implementation of the language-specific code, and minimzes the number of entry points into the C++ DLL that must be called using a native-code interop technology such as JNA, ctypes, pinvoke or DL. Memory Management The IE driver utilizes the Active Template Library (ATL) to take advantage of its implementation of smart pointers to COM objects.
