Hi Klement,
Thanks for your reply!
The exact problem statement is , we are trying to send some events from VPP
to client app , but client is not able to read those events api messages
until it has some pending requests. So as a work-around we are sending
control ping after few seconds from client to have at least one request
pending from client side.
Thanks,
Chetan Bhasin
