SproutCore DataSource POST is redirecting automatically, so the response parameter of didCreateRecord is a GET response instead of a POST response

gistfile1.js

createRecord: function(store, storeKey) {
	
	if (SC.kindOf(store.recordTypeFor(storeKey), Library.Slideshow)) {
		
		SC.Request.postUrl('/api/slideshow').header({ 'Accept': 'application/json' }).json()
		.notify(this, this.didCreateRecord, store, storeKey)
		.send(store.readDataHash(storeKey));
		return YES;
		
	}

	return NO;

},

/**

didCreateRecord: function(response, store, storeKey) {
	console.log('didCreateRecord');
