Constants

const (
	// MaxCacheControlAge is the maximum age in a cache-control
	// header supported by most browsers. Notably, IE9 will consider
	// as stale resources with a max-age greather than this value
	// (2^31).
	MaxCacheControlAge = int(^uint32(0) >> 1)
)

Variables

var (
	// MaxExpires is the maximum safe HTTP Expires header value.
	// It represents the UNIX biggest timestamp representable with
	// 32 bits.
	MaxExpires = time.Unix(int64(MaxCacheControlAge), 0).UTC()
)

Functions
