Functions

func Get

func Get(key string) ([]string, bool)

Get returns a value from cache at key

func InitialiseSessionCache

func InitialiseSessionCache() (*ristretto.Cache, error)

InitialiseSessionCache creates a cache manager that stores keys and values in memory

func NewSessionKey

func NewSessionKey() string

Types

type DatasetCache

type DatasetCache struct {
	Datasets []string
}

DatasetCache stores the dataset permissions and information whether this information has already been checked or not. This information can then be used to skip the time-costly authentication middleware DatasetCache==nil, session doesn't exist DatasetCache.Datasets==nil, session exists, user has no permissions (this case is not used in middleware.go) DatasetCache.Datasets==[]string{}, session exists, user has permissions
