The caption says it all. By default, JSF performs periodic checks of Facelets views changes And the check can be configured through context parameter
javax.faces.FACELETS_REFRESH_PERIOD
Further, there is this method in abstract class FaceletCache
public abstract boolean isFaceletCached(URL url);
which can be overridden to cache Facelet or not.
I was looking at the default implementation of FaceletCache but couldn't get to know whether Facelets are cached by default or not.
/**
* Default FaceletCache implementation.
*/
final class DefaultFaceletCache extends FaceletCache<DefaultFacelet> {
@Override
public boolean isFaceletCached(URL url) {
com.sun.faces.util.Util.notNull("url", url);
return _faceletCache.containsKey(url);
}
//.....
}
And when should one really cache Facelet?
