1. As far as we know, IE on windows is implemented using AtiveX.
2.NPAPI is about to be abandoned, PPAPI Google is about to be abandoned, and there is no way to embed this plug-in model.
3. Now there are WebGL and other technologies to achieve complex rendering of web pages, but if I am a more complex application, using this technology to achieve web-server technology is not displayed, is there any good plan to embed local programs into the web page?
