I'm using preview 5 and trying to get some partial page caching.  I don't want to use a user control.  I am instead using RenderAction() to render one of my controllers.  Then I'm putting [OutputCache(Duration=1200)] on my controller method, but its still firing every time and not caching when called in this way.

 Is this not supported yet?  Is there another way i should be doing this?

Thanks,
Craig

We don't yet support partial view caching.  We've been looking into how we can support this, but unfortunately it's very complicated to get this working properly, so we've prioritized other bugs and features ahead of it in the meantime.
