HAProxy Stats over HTTPS only

Help!

hi, it works but that brings me to another little question - how do I enable HSTS in HAProxy 1.5? My haproxy.cfg goes like this

listen stats
## HAProxy stats web gui.
	bind 0.0.0.0:443 ssl crt /etc/ssl/dblb.testcert.com.combined.pem no-sslv3 ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS
	mode http
	stats enable
##	stats hide-version
	stats uri /haproxy_stats
	stats realm HAProxy\ Statistics 
	stats auth admin:admin_pwd
	stats admin if TRUE

Thanks once again for the help

Cheers,
