COREDNS-HTTPS(7)

🎀 COREDNS-HTTPS 🎀

okay so this is the https plugin from the CoreDNS Plugins manual, section 7 — yes bestie, we're reading the docs together, it's a whole vibe 💅

✨ NAME ✨

https — literally configures your DNS-over-HTTPS (DoH) server options. that's it, that's the whole job 🫶

🌸 DESCRIPTION 🌸

the https plugin lets you set the parameters for the DNS-over-HTTPS (DoH) server so you can fine-tune the security posture and the performance of the server. both. at once. iconic behavior honestly ✨

🚨 important heads-up bestie: this plugin can only be used once per HTTPS listener block. one and done, no double-dipping 💀

💖 SYNTAX 💖

https {
    max_connections NON_NEGATIVE_INTEGER
    max_streams NON_NEGATIVE_INTEGER
}

• max_connections NON_NEGATIVE_INTEGER — caps the number of concurrent TCP connections to the HTTPS server. if you don't specify it, the default is 200. set it to 0 and it's unbounded — no cap, no limits, main character energy 🔥
• max_streams NON_NEGATIVE_INTEGER — caps the number of concurrent HTTP/2 streams per HTTPS connection. this is the little guardrail that stops one single connection from spawning unbounded streams and absolutely devouring your server resources 😭 default is 250 if you don't specify it. set it to 0 and you get the underlying HTTP/2 transport default instead 🦋

🌈 EXAMPLES 🌈

setting custom limits for max connections and streams

like, if you want both numbers under your control:

https://.:443 {
    tls cert.pem key.pem
    https {
        max_connections 100
        max_streams 100
    }
    whoami
}

setting both values to 0 to disable the CoreDNS limits

this one is the "turn off the limits" move — unbounded connections plus the underlying HTTP/2 transport stream default. and ngl, this matches how CoreDNS behaved before v1.14.0, so it's your time machine back to the old days 🕰️✨

https://.:443 {
    tls cert.pem key.pem
    https {
        max_connections 0
        max_streams 0
    }
    whoami
}
