HTTP multistreaming loader

HTTP multistreaming loader is a small piece of software written in JavaScript that gives you full control over http downloads, it relies on built-in range-requests feature of the HTTP protocol allowing to request only specific part of a file from the server. Using it you can:

• Easily request only parts of the file
• Boost downloading speed on the client side by streaming the same file over http from multiple locations
• On the contrary, limit downloading speed by specifying maximum value
• Provide visual progress bar for the user

HTTP streaming plugins for Flowplayer and Media Strobe Playback Flash players, mp4 extractor and scrubber preview plugin for Flowplayer html5 and videojs players all use internally HTTP multistreaming to do the heavy lifting.

All major browsers are supported with Internet Explorer starting from version 8. To support the required communications between loaders based on iframes when requests are made to a different domain in Internet Explorer 7 Flash LocalConnection could be used however it has a limit of 40k per request and support for it was discontinued.

Examples

And finally with speed limit set to 100kb/s:
