So you were correct, you should be setting the dispatched flag to false, but in order to prevent an infinite loop you need to to test from within your plugin if it has already run or not. This can be done with an $_enabled property:
protected $_enabled = true;
public function preDispatch(Zend_Controller_Request_Abstract $request)
{
if (true === $this->_enabled) {
$request->setDispatched(false);
// Prevent this plugin from running on the next dispatch loop
$this->_enabled = false;
}
}
If you want to skip the current action but continue with the rest of the dispatch loop, alter the request (perhaps by setting it to a dummy controller/action) and set the dispatched flag to false.
Other than that, I don't think there's a way to exit the dispatch loop unless you use exit.

Hello,this is not working.If i Register my Cache Plugin to my Frontcontroller an set the $request->setDispatched(true) in the PRE DISPATCH() (i'll stop the hole dispatch process) - the script run into endless.a Snipped from the ZF doku.preDispatch() is called before an action is dispatched by the dispatcher. This callback allows for proxy or filter behavior. By altering the request and resetting its dispatched flag (via Zend_Controller_Request_Abstract::setDispatched(false)), the current action may be skipped and/or replaced.my Plugin.class Default_Plugin_Cache extends Zend_Controller_Plugin_Abstract{public function preDispatch(Zend_Controller_Request_Abstract $request){$this->_sCacheString = md5( $request->getRequestUri() .

That should inform the dispatcher that the request has already been fulfilled and continue on to postDispatch().

is it possible to Implement a Hook/Callback to stop dispatching in the FrontController in a official version of ZF ?
Thanks
