### Policy Variables

You can use policy variables in the *Resource* element and in string comparisons in the *Condition* element.

# Remove rule from siteb
./mc ilm rule remove --id "${id}" siteb/bucket
sleep 30s # allow to replicate

# sitea should still contain the transition portion of rule
transitionRuleDays=$(./mc ilm rule list sitea/bucket --json | jq '.config.Rules[0].Transition.Days')
expirationRuleDet=$(./mc ilm rule list sitea/bucket --json | jq '.config.Rules[0].Expiration')

	// Presign is not needed for anonymous credentials.
	if accessKeyID == "" || secretAccessKey == "" {
		return errors.New("Presign cannot be generated without access and secret keys")
	}

	// FIXME: Remove following portion of code after fixing a bug in minio-go preSignV2.

	d := UTCNow()
	// Find epoch expires when the request will expire.
	epochExpires := d.Unix() + expires

	// Add expires header if not present.
