# To demonstrate various ways to composing complex pages with cached invoke

### Each parts render themselves with own cache control

The outer most content is cached for 20 seconds, using the CacheFor annotation. ${new Date()}

this part is never cached: `invoke controllers.more.Portlets.panel1("\"never cached\"")`

this part is cached for 10 seconds. Note the timeout spec with invoke overrides CacheFor annotation. `a controllers.more.Portlets.panel2(b), "10s"

Let's evict the panel2 cache!

this part is cached for 4 seconds, specified with CacheFor annotation in the controller. `a controllers.more.Portlets.panel3(a + b)

Let's evict the panel3 cache!
