Hi, Excuse
me, I have asked this question again. I asked this question 10 days ago, but
I've got no response. Question: Will the
<create-subscription> request get a positive response, when the result of
<filter> and <named-profile> is nothing? If the
subscription is successful in the circumstances, no event will be sent through
this session. The client and server have to keep an empty session. When a new
event is generated, the server must check whether the event matches to the
filter conditions. It's
waste of resources. So, I believe the subscription should be failed. Thanks Yan |
