NAME¶
https - configures DNS-over-HTTPS (DoH) server options.
DESCRIPTION¶
The https plugin allows you to configure parameters for the DNS-over-HTTPS (DoH) server to fine-tune the security posture and performance of the server.
This plugin can only be used once per HTTPS listener block.
SYNTAX¶
https {
max_connections POSITIVE_INTEGER
}
- •
- max_connections limits the number of concurrent TCP connections to the HTTPS server. The default value is 200 if not specified. Set to 0 for unbounded.
EXAMPLES¶
Set custom limits for maximum connections:
https://.:443 {
tls cert.pem key.pem
https {
max_connections 100
}
whoami }
Set values to 0 for unbounded, matching CoreDNS behaviour before v1.14.0:
https://.:443 {
tls cert.pem key.pem
https {
max_connections 0
}
whoami }
