Take a look at `varnishlog` while you have traffic flowing thru - you'll feel like you've seen the light :) Also, read the vsl-query docs: https://www.varnish-cache.org/docs/trunk/reference/vsl-query...

In terms of introspectability, Varnish (afaik) is without equal.

Totally agreed!

I believe that the power and utility of VSL are so underestimated and overlooked that I don't know where to start...
