pub const DEFAULT_RETRY_AFTER: u32 = 60;Expand description
Default Retry-After header value (seconds) on HTTP 429 responses
emitted when a per-(cluster, source-IP) connection limit is hit. 0
omits the header — Retry-After: 0 invites an immediate retry that
defeats the limit. TCP rejections do not emit this value (no HTTP
envelope), but the field is accepted for symmetry.
