## Retomando com `Last-Event-ID` { #resuming-with-last-event-id }

Quando um navegador se reconecta após uma queda na conexão, ele envia o último `id` recebido no cabeçalho `Last-Event-ID`.

Você pode lê-lo como um parâmetro de cabeçalho e usá-lo para retomar o stream de onde o cliente parou:

      def splitJobName = jobName.split('/')
      if (splitJobName.length > 1 && splitJobName.last() ==~ /^([a-zA-Z0-9_\-]+=[a-zA-Z0-9_\-&\.]+,?)+$/) {
        def baseJobName = splitJobName.dropRight(1).join('/')
        tag baseJobName
        tag splitJobName.last()
        value 'Job Name', baseJobName
        def matrixParams = splitJobName.last().split(',')
        matrixParams.collect { it.split('=') }.each { param ->

)

func Test_metaCacheEntries_sort(t *testing.T) {
	entries := loadMetacacheSampleEntries(t)

	o := entries.entries()
	if !o.isSorted() {
		t.Fatal("Expected sorted objects")
	}

	// Swap first and last
	o[0], o[len(o)-1] = o[len(o)-1], o[0]
	if o.isSorted() {
		t.Fatal("Expected unsorted objects")
	}

	sorted := o.sort()
	if !o.isSorted() {
		t.Fatal("Expected sorted o objects")
	}

func (client *storageRESTClient) IsOnlineWS() bool {
	return client.gridConn.State() == grid.StateConnected
}

// LastConn - returns when the disk is seen to be connected the last time
func (client *storageRESTClient) LastConn() time.Time {
	return client.restClient.LastConn()
}

func (client *storageRESTClient) IsLocal() bool {
	return false
}

`data` y `raw_data` son mutuamente excluyentes. Solo puedes establecer uno de ellos en cada `ServerSentEvent`.

## Reanudar con `Last-Event-ID` { #resuming-with-last-event-id }

Cuando un navegador se reconecta después de una caída de la conexión, envía el último `id` recibido en el header `Last-Event-ID`.

Puedes leerlo como un parámetro de header y usarlo para reanudar el stream desde donde el cliente se quedó:
