func Parse ¶

func Parse(v string, now time.Time, limit time.Duration) (time.Duration, bool)

Parse reads a Retry-After value, either delay-seconds or an HTTP-date, relative to now. It reports false for an empty, malformed or negative value, and for a date that is not in the future (usually clock skew), so callers apply their own default. A positive limit caps the delay: a huge value neither overflows nor pauses the caller for longer than it allows.
