RE: [flexcoders] Flex, Remoting and more

The danger of persistent connections is one of scaleability…and of trying to manage a reliable protocol across those connections (as opposed to the relative simplicity of a request/response protocol).   A hybrid that we’ve used is a server-based “collector” (listener) and clients that “ping” (a euphemism for lightweight polling) to see if there’s something for them to do.   The other advantage of polling is “pacing” – you can manage the rate at which events/messages get exchanged even when “bursts” of events occur.   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Alberto Albericio Salvador Sent: Monday, June 27, 2005 6:57 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Flex, Remoting and more   Hi all, I've been reading about "connecting" flex client applications using Flash Communication Server(FCS) and shared objects. Thats seems to cover the needs for developing chat-like applications... Now, imagine I have an external "Notification server" (yukon notification server, or whatever) And I want FCS to listen *persistently* to this server. With FCS and Remoting I know how to POLL a database "1 time or every 10 seconds" and format that answer to feed the FCS but HOW can I create a persistent link to a notification server,socket server or similar, get the data this server is pushing, format this data and pass it to the FCS? So basically, I want to know how to replace POLLING with PERSISTENT LISTENING. Example application: A Flex application that shows the queue of  a call center. When a new call arrives, it is shown in every client running the application. And it is the call center notification server that tells the FCS it has received the new call and NOT the FCS that polls the queue of the notification server to see if there is any new call pending.
