It is right that the cache is not done in a per-user basis - still, it is an option. The downside is that you have to associate to which user the data belongs by yourself. Its an extra effort, so its better be worth that effort - in my case the page is the same for all users, so this is not a problem.

Also, this is not an _Scala_ characteristic - it is the way Play Framework works. Other Scala frameworks might (and most do) things differently.
