Does Amazon API Gateway support endpoint URL with port numbers?

I tried using Amazon API Gateway and tested it on an endpoint URL. It works fine if the server is listening on port 80.

However, if I give the endpoint URL with a different port, (say http://ift.tt/1PzPurc) it gives an error. If I visit this URL directly on a browser(GET method), it gives me the required output.

Is this a feature that is not available yet in AWS API Gateway?
