/**
* Abstract special page class with scaffolding for caching the HTML output.
*
- * To enable the caching functionality, the cacheExpiry field should be set
- * before parent::execute is called (and it should be called from execute).
- *
* To add HTML that should be cached, use addCachedHTML like this:
- * $this->addCachedHTML( array( $this, 'displayCachedContent' ) );
+ * $this->addCachedHTML( $callback );
*
+ * The callback function is only called when needed, so do all your expensive
+ * computations here. This function should returns the HTML to be cached.
+ * It should not add anything to the PageOutput object!
+ *
* Before the first addCachedHTML call, you should call $this->startCache();
* After adding the last HTML that should be cached, call $this->saveCache();
