Thanks for the details. I already figured this out when using the HTML client, the items were added dynamically in a specific order.

However, I need to know if the order assigned to each item is the same as the order returned by the MetaAdapter.getItems ? That would help keep the same order to the end-user as it is stored in the backend DB.

2) Also, I'd like to know how can I manage Single-Singon ?
Basically, suppose I am using Apache to authenticate the user and manage HTML pages.
Lightstreamer would be a standalone instance only serving push information.
How can I automatically have Lightstreamer authenticate the same Apache user without prompting for the user/password again ?
