    Description copied from interface: Asset
    
    Returns true if the Asset is invariant (meaning that it returns the same value from Asset.toClientURL() at all times). Most Assets are invariant. Assets that are used as binding values will be cached more aggressively by Tapestry if they are invariant. This default implementation returns false
    
    Specified by:
    
    isInvariant in interface Asset
    
    Returns:
    
    true if invariant
