	function parseIdFromLocation(url) {
	var queryPos = url.indexOf('?')
	if (queryPos > 0) {
	url = url.substr(0, queryPos)
	}
	var parts = url.split('/')
	var result
	do {
	result = parts[parts.length - 1]
	parts.pop()
	// note: first result can be empty when there is a trailing slash,
	// so we take the part before that
	} while (!result && parts.length > 0)
	return result
	}
