About Lightstreamer
Lightstreamer is a high-performance, Java-based push/streaming engine based on the AJAX-Comet paradigm that delivers real-time textual data to Web browsers and to desktop applications. When using browsers as a client, nothing is installed or downloaded (no applets or ActiveX, but only pure HTML/JavaScript). Lightstreamer was originally developed by the Financial Systems Integration activity of privately held Par-Tec SpA group (founded in 1998). In 2004 a separate company was formed within the group as an ‘ISV’ to provide Lightstreamer 'Push' middleware solutions for streaming real-time Market Data, or any live information, to web browsers and custom application clients. Lightstreamer is compatible with many browsers on the market, such as Internet Explorer, Firefox, Opera, Netscape, Safari, etc. For more information see www.lightstreamer.com  where several on-line demo’s are also freely accessible.
