$0An activex program is needed to integrate with a website. It is similar to an offline installation program. The activex itself is small, but it is able to download a large program with multi-thread downloading. It is similar to some installation programs where the user downloads a small exe first, and then the exe will download a large program for the user to install. The user must be able to click on a link on the website, and then the exe would automatically run and start downloading a file.$0
