Say I download an executable like Pycharm from Jetbrains.com. HTTP was used to deliver contents of the website - is this also used when I download the file? I read that FTP was used but also saw it's been disabled for modern browsers - what is the recommended protocol?
Also, if there is a network disruption, sometimes I can resume the download without losing progress. Is this because a "session" was created and I can rejoin the session and continue the download? What determines how long this period lasts for before I have to restart the download from scratch?
