Direct Actions are action methods that can be called without a WOSession. As opposed to Component Actions, where a WOSession is required and various form values are bound as objects, Direct Actions perform much more like traditional web frameworks where the form values are accessed via WORequest's formValues dictionary and cookies. Direct Actions are very useful for building stateless, high-performing websites, though you lose some of the easy-of-development that makes WebObjects provides with Component Actions.


Direct Actions would also be good to use if you don't need the additional convenience of the Component Actions, simply because they come without any of its disadvantages. However, it's quite difficult to create a whole WO application without creating a WOSession and most of the time, you're going to need it anyway.
