Stop Elastic Load Balancer From Revealing Internal Private IP

It's come to my attention that the internal IP of ec2 instances behind an ELB, even when in a private subnet, are revealed when a particular type of request is issued.

telnet site_url 80
GET / HTTP/1.0

And the returned headers:

HTTP/1.1 301 Moved Permanently
Cache-Control: max-age=1209600
Content-Type: text/html; charset=iso-8859-1
Date: Thu, 26 Mar 2015 18:47:22 GMT
Expires: Thu, 09 Apr 2015 18:47:22 GMT
Location: https://10.0.7.35/
Server: Apache
Content-Length: 226
Connection: Close

Naturally this occurs with an open ssl request on 443 as well.

Is anyone aware of a resolution or workout for this problem? I know IIS suffers from the same symptoms but my problem is specific to AWS ELBs.
