How to get events from a web service ?

[Navin Mishra]

Hi,

Is there a way to get events from a web service in platform independent
way ? Could a long standing HTTP GET request be submitted from a client and
server respond to that request when an event comes ? Or perhaps HTTP
chunking could be used ?

Thanks in advance and regards

Navin

WCF supports callback contracts. I suppose they could be used for something
like this. I suggest you consider the cost, though. You'll be turning
clients into servers.

Thanks. Is there any other way like long standing HTTP GET request or HTTP
chunking so that a client on any platform could get events ?

Thanks again and regards

You could look at using a product like NServiceBus that allows for
pub/sub (but then again I'm not sure if you own both ends of the wire in
this case). Worth taking a look at though.
