Gets and sets the property ResponsePagePath. The path of the custom error page (for example, /custom_404.html). The path is relative to the distribution and must begin with a slash (/). If the path includes any non-ASCII characters or unsafe characters as defined in RFC 1783 (http://www.ietf.org/rfc/rfc1738.txt), URL encode those characters. Do not URL encode any other characters in the path, or CloudFront will not return the custom error page to the viewer.
