title: Play - Sharing objects among requests with no need for persistence
body: <p>In my Play application, I need to share some objects in between several requests, but have no need for any type of long term persistence.  The objects are too big to be stuffed into a cookie.  I could serialize them to a relational database, but that seems to heavy for my needs: it would suffice to somehow say "Keep this object around for 10 minutes, make it accessible to all threads, then throw it out"</p>
  
  <p>How can I do this?</p>
