Subject Re: Publishing to the Data Sink url failed
Date Wed, 01 Dec 2010 05:05:48 GMT
Hi,

I am still stuck at this. Can anyone please help me.

Also please help me understand the following point.

"This is not part of Savan implementation. Subscriber is supposed to "know"
his own data sink."

So how does the subscriber know some data is published? Will it keep on
polling the sink at periodic interval? (Please excuse my lack of
understanding.)
