<p class="MsoNormal">You need some way to address HTTP sessions. Otherwise you will be randomly logged out if your request goes to a different dashboard host than the one you logged in on. One way is to set up a shared memcached cluster that each dashboard
host talks to--configure the "CACHE" setting in the local_settings.py file. [1] Another way is to configure your load balancer with session stickiness/affinity.

<p class="MsoNormal">I wonder if it is worth to do it, or it is not treated because the Dashboard is a simple stateless service which can just be "mirrored" on another node without any particular setup.<o:p></o:p></p>
