[Question] A feature to propagate context within trace #5266
Title: [Question] A feature to propagate context within trace
I'd be grateful if you could tell the reason why does Envoy entrust propagation of context to application.
It would certainly be great if this was possible - however the problem is that the Envoy proxy has no way of knowing which outbound requests were caused by which inbound requests.
The only way that an outbound request can be correlated to an inbound request, and therefore reported as being part of the same trace instance, is if some correlating information from the inbound request is passed to the outbound request - which can only be achieved in the application code.
