 And now the fun part. You can replace any partial rendering with the ViewHelper ``s:renderInclude``.  
 That Partial will only be rendered once every 5 minutes for the complete Site (Site Configuration Site (not Page)).  
 The only differentiation will be done by **site config**, **language** and the provided **name**.  
+Optionally, you can add **cacheLifeTime** to define the lifetime of the partial in seconds.
 If you include want to render the same partial with diffrent arguments it will still be the same content if you have the same name.
