Types

type CacheType

type CacheType string

CacheType describes the type of cache shall be used, which its value is the content of the `Cache-Control` header that is being populated

const (
	// CacheTypeStatic describes the resource should never be changed and therefore is safe for long-term caching
	CacheTypeStatic CacheType = "public, max-age=31356000"
	// CacheTypeDynamic describes the resource as if it is a valuable-to-cache dynamic resource
	CacheTypeDynamic CacheType = "public, max-age=300, must-revalidate"
	// CacheTypeNoCache describes the resource should always not be cached
	CacheTypeNoCache CacheType = "no-store"
)
