Hello,
Instana has support for W3C headers, if the incoming request has W3C headers, we can propagate the traceContext. I hope you mean about HTTP requests.
I understand from here that it is possible to transform CloudFlare headers. So, if we can transform the cloudFlare header to comply with traceParent(W3C), we can read it and can propagate it. I hope this helps.
