title: Clustering session storage location
body: <p>Regarding <a href="http://wiki.cloudbees.com/bin/view/RUN/AppClustering" rel="nofollow">app clustering</a>, do we have to create a separate session storage location? You mention several options on that page (MySQL, CLoudant, RDS, etc.), does that mean we have to setup one of these and have it interact with our cluster somehow? Or is that all this automatically setup through <a href="http://wiki.cloudbees.com/bin/view/RUN/AppSessionStores" rel="nofollow">session stores</a>? If it's setup, is it setup using CloudBees MySQL behind the scenes?</p>
