download: Lightstreamer 5.0, codename Colosseo.
Lightstreamer includes now full support for WebSockets, the new Web standard from IETF that enables bi-directional, full-duplex communication over the Web. Even if WebSockets are not yet universally supported by browsers and network infrastructure, Lightstreamer is able to automatically choose the best transport, among the many available, based on the characteristics of each client. The Stream-Sense algorithm of Lightstreamer will make sure that the real-time data will travel to and from any possible client, connected through any existing proxies and firewalls.
For a historical perspective on Lightstreamer and WebSockets, see this previous article.
Lightstreamer Server 5.0 has increased performance, scalability, and security, in addition to a simpler installation procedure under both Linux and Windows.
There is now full support for cross-origin connections, so that in most cases you don’t have to use the same domain name for the web server and the Lightstreamer server.
The new Stream-Sense algorithm, besides supporting WebSockets (in addition to previous transports), is much faster, with impressive performance boost on session start up.
Many other features are available as part of the new JS client library, including a new logging and error management facility as well as new ready-made widgets (a new status indicator and new data grids).
Read through the detailed changelog to learn about all the changes to Lightstreamer Server and to the Client and Adapter APIs.
