Smart polling mode benefits...

[ddhanis]

Hi All,
Today I run the StockListDemo using several LS servers that sit behind a load balancer device (juniper DX Accelerator ).

As I noticed, the streaming mode has changed from "Streaming Mode" to "Smart Polling Mode". Can anybody give me some explanation as to why this situation happens ? And what are the consequences and benefits of this situations ?

Thank you all in advance.

best regards,Dyan Dhanisworo

Hello,

the web client switches from streaming to smart polling mode after a timeout if no data was received from the opened streaming session.

from http://www.lightstreamer.com/products.htm :
Stream-Sense and Smart Polling
If a client is connected through a network infrastructure that blocks any form of streaming, then Lightstreamer is able to send the updates via a smart polling mode. The Web Client of Lightstreamer automatically detects if streaming is not supported (through the Stream-Sense feature) and in this case it switches to smart polling mode.

Note that you can configure the smart polling behavior: http://www.lightstreamer.com/docs/client_web_jsdoc/Policy.html

Smart polling is also known as long-polling.
