Description
This issue is automatically created based on existing pull request: #28944: [vcl] Better debug
Detecting if the response is a hit usingthe x-varnish header is flaky
and notably doesn't work in a multi-tier setup.
On top of this, HIT/MISS is a false dichotomy (https://info.varnish-software.com/blog/using-obj-hits)
and while I'd like something more detailed like
https://docs.varnish-software.com/tutorials/hit-miss-logging/ (tech
version of the blog), I recognize that it's "a lot" of VCL, so this
commit only differentiates between hits, misses and passes, the latter
being pretty useful to identify while debugging.
note: all versions have been changed for the sake of consistency
but both the 4.x and 5.x series have been EOL'd a (long) while ago and users
should be encouraged to upgraded as soon as possible.
