I really wonder how torrent downloads can be resumed at later point of time. If such a technology exists, then why is it not possible in browsers?
It is often not possible to pause a browser download so that it can be resumed at a later point of time. Often, the download will start again from the beginning. But in the case of a torrent download, you can resume anytime.
One reason I could think of is that a browser makes an HTTP connection to the server which contains the file, and when this connection breaks, there is no data regarding how much file was saved so no resume is possible.
Is there a fundamental reason why torrent downloads are easier to resume than web downloads?
