Description

Good morning sirs.
On router I use Dnsmasq with mihomo as forward server. It's faster for AdBlock with simple blocklist like oisd or hagezi. It has more feature like min/max cache ttl, stale cache etc. Since mihomo only used as resolver, can we have an option to disable dns cache in mihomo? Maybe also an option to change cache capacity. I looked at the code it use fixed capacity of 4096?
Thank you sirs 🙏
