RE: OSCache and MVC

The needs (therefore the strategy) for caching varies a lot from application
to application.

The usual strategy I have used with a lot of success for web applications is
to have caching in the persistence tier (ie Hibernate, Entity beans) and
caching page fragments using oscache. This is very simple, and gives amazing
performance.

The way I do it is first; no caching. Then based on an analysis of the
caracteristics of the site, use oscache to cache fragments of page. Then
analyze queries to the db and activate caching in the persistence tier. I
like to do the front end first because if you do it the reverse order, you
might end up doing some useless caching in the persistence tier
