Adding iphash to Upstream has no effect

[BnMcG]

My Puppet config looks as so:

# NGINX config
        class { 'nginx': }

        $upstream_config = {
                'ip_hash'   => '',
                'keepalive' => '20',
        }

        nginx::resource::upstream { 'app_app':
                members => [
                        '10.99.0.10',
                ],
                upstream_cfg_prepend => $upstream_config,
        }

        nginx::resource::vhost { 'app.app.com':
                proxy => 'http://app_app',
                ipv6_enable => true,
        }

When applying my configuration, the "keepalive" value seems to be set in the actual configuration file, but iphash does not:

upstream app_app {


  keepalive 20;

  server     10.99.0.10  fail_timeout=10s;
}

Have I done something wrong? Why isn't ip_hash being enabled? I installed the module today so I guess I have the latest version.

After a little playing around, this seems to work if I specify:

'ip_hash'   => ' ',

(Note the extra space between the ''s), but specifying an empty value as I saw in the documentation in the module source code does not work.

As mentioned in #563, I tried using '' (via hiera), and it did seem to work. Are you still able to reproduce this issue @BnMcG (with a recent version of the module)?
