Web seeding was implemented in 2006 as the ability of BitTorrent clients to download torrent pieces from an HTTP source in addition to the swarm. The advantage of this feature is that a site may distribute a torrent for a particular file or batch of files and make those files available for download from that same web server; this can simplify seeding and load balancing greatly once support for this feature is implemented in the various BitTorrent clients. In theory, this would make using BitTorrent almost as easy for a web publisher as simply creating a direct download while allowing some of the upload bandwidth demands to be placed upon the downloaders (which normally use only a very small portion of their upload bandwidth capacity). Read morehere. BitComet implemented this feature from version 1.14, and supports the Getright Webseeding spec.
If you know the HTTP source of a file that is the same as the source file (or the URL of the source file), you can enter the URLhere. This is helpful for downloaders to acquire data, or in other words, download, from the HTTP server, in this way improving the downloading speeds and torrent health.
When the torrent content is for a single file, a specific URL should be entered. For example:
If the published torrent is for a directory (muti-files), file name can be omitted in the URL you enter. But please note that the URL must end with a slash ”/”. For example:
Tip: You can enter several mirror sites in the list. One for each line only.
After you finished all the settings and modifications, please do not forget to hit the “Make torrent” button, to finish.
Note: Remember! When you have made a //.torrent// file, you must publish the torrent on a torrent site. And please make sure BitComet is started and seeding the task, so that others can download from you once they saved the //.torrent// file.
