Clarification on Solicited vs Regular Snapshot Expected by POP on Initial Request

rajkumargajam

When a client requests an item for the first time and the POP subsequently requests that item from the provider, can you confirm what the POP expects in the provider’s response?

Specifically, does the initial response from the provider need to be marked as a solicited snapshot, or can it be sent as a regular (unsolicited) snapshot without impacting stream initialization or state handling within the POP?

Any clarification on the POP’s expectations and required behavior would be appreciated.

Thank you.

If it is a response to a request message, it must be a solicited refresh message.

If provided as a response to an RsslRequestMsg, the refresh is a solicited refresh. Typically, solicited refresh messages are delivered only to the requesting consumer application

If some kind of information change occurs (e.g., some kind of error is detected on a stream), an upstream provider can push out an RsslRefreshMsg to downstream consumers. This type of refresh is an unsolicited refresh. Typically, unsolicited refresh messages are delivered to all consumers using each consumer’s respective stream.
