Comment (by david):
This behavior makes it basically impossible to determine your actual
request cache hit/miss ratio. I understand the logic behind the
behavior, but I think it's nearly useless in any real-world scenario.
Because of this behavior I cannot implement the VCL I provided here
because of the "invalid" hit ratio numbers I get from varnishstat. The
whole point of this VCL is to increase my hit ratio by serving banned
users a cached "you're banned" page. Instead of increasing the hit ratio,
it was dropped to 1/10th of what it was.
If you intend to keep this behavior, I'm done complaining, but I at
least think changing this is worth considering and discussing. If an
upcoming version has a way to check two hashes in one request without
restarting then I can certainly wait for that.
Regards,
