I doubt we'll want to merge this, as it's unneeded in trunk.

| Yes it worked but didn't do the job I expected. After first request to
| the site I want the browser to be always directed to the same backend
| (due to sessionId management). I think I have to use Cookies to
| achieve this or just serve static content with varnish and use haproxy
| as backend for dynamic content.
| 
| I'm just wondering which solution is best :
| - varnish as frontend to haproxy
| - haproxy as frontend to varnish

Either should work fine, but test.  You could just also move all static
content to a different host name and let haproxy be the dynamic one and
varnish the static one.
