Is there a straightforward way to assign a unique Request ID (eg.
x-request-id), and have it logged and passed to backends? I’m working on improving transaction tracing in our apps, and it’d be nice to extend that to the CDN too.
Looks like Varnish has a X-Varnish header which will do part of that (combined with a timestamp), but I’m not sure if I can get that exposed through Fastly?
