Last-Event-ID"</a></code> HTTP
 request header as part of a new connection request sent to the SSE endpoint. Upon a receipt of such reconnect request, the SSE
 endpoint that supports this negotiation facility is expected to replay all missed events. Note however, that this is a
 best-effort mechanism which does not provide any guaranty that all events would be delivered without a loss. You should
 therefore not rely on receiving every single event and design your client application code accordingly.
