We are currently using a Internet cloud provider to host our SaaS platform. The platform consists of a Firewall - Cloud Provider SLB - -
Apache Web Server - HAPROXY SLB - Liferay Platform
We have had to use HAPROXY because of an issue with the cloud providers SLB that meant we were unable to use it for load balancing the Liferay platform applications.
I have implemented HAPROXY in our secure tier and that seems to do the trick of load balancing the requests quite adequately.
However during testing we encountered a functional issue whereby selecting a sub-menu from the web portal resulted in the application hanging, using an http analyser we saw that the request being passed back to the users browser was in http, from discussing this with the software vendor it transpires that the Liferay application has some hard-coded http links, and that other customers have worked around this by using physical NLB's such as F5 and redirecting the http traffic to https.
The entry in the HAPROXY logs reads:

From reading through the forums and other sites it looks like we should be use to use HAPROXY to redirect the traffic to https, but try as I might I cant get it to work.
This is our HAPROXY configuration:

I have tried following the articles listed posted on http://stackoverflow.com/questions/13227544/haproxy-redirecting-http-to-https-ssl and http://parsnips.net/haproxy-http-to-https-redirect/ but that hasn't made any difference.
Am I on the right track with this or are we trying to achieve the impossible?, I'm hoping I'm just being an idiot and one of you good people can point me in the right direction.
