[Twisted-Python] server push data to client
hi, what could be the way(Producer/Consumer?) and simple,basic example to push data(~10Kb) from Twisted based server(that listening for incoming requests) into client side(for example FLEX) not as a response to the incoming request, but occasionally, triggered by server side??? In traditional client/server arch, the server is listening, accepting and responding to the client's requests, but here I'm looking for something that initiated from server itself and pushing data to client. Appreciate the help.

In HTTP, the client can't open server sockets. The workaround is poll to the server or open a persistent connection to the server. Some clients can't open server sockets (they are behind a firewall) and you need make the same tricks. Orbited is a comet (server push) framework based on Twisted. http://orbited.org/ Cometd (the twisted version) can be another example: http://svn.cometd.com/trunk/cometd-twisted/ http://cometdproject.dojotoolkit.org/ Regards, Javi
Thank you. Did anyone tried AmFast: http://code.google.com/p/amfast/ ??? Quoting lasizoillo <lasizoillo@gmail.com>:
