see also "WCF push to client through firewall"
I need to have a WCF client that connect to a WCF server, then when some of the data changes on the server the clients need to update its display.
As there is likely to be a firewall between the clients and the server.
- All communications must be over HTTP
- The server can not make an (physical) outgoing call to the client.
As I am writing both the client and the server I do not need to limit the solution to only using soap etc.
I am looking for built in surport for "long polling" / "Comet" etc
Thanks for the most informative answer from Drew Marsh on how to implement long polling in WCF. However I thought the main “selling point” of WCF was that you could do this sort of thing just by configuring the channels to be used in the config file. E.g I want a channel that logically two way but physically incoming only.
