Zend - Conditionally reroute all pages

Question

I'd like to be able to reroute or redirect all requests to my site to a specific page, if a conditional passes. I'm assuming this would have to be done somewhere in the bootstrap or with the dispatcher, but I'm not sure exactly what the best/cleanest way to go about it would be.

No .htaccess redirects since a condition needs to be tested for in PHP

Here's what I'd like:

if( $condition ) {
    // Redirect ALL Pages/Requests
}

// else, continue dispatch as normal...

The idea here is that we can setup the entire website and send everything to a splash page until a specified date/time, at which point it would 'auto launch' itself essentially.

Indeed, I'd go for a plugin.

In library/My/Plugin/ConditionallyRedirect.php:

class My_Plugin_ConditionallyRedirect extends Zend_Controller_Plugin_Abstract
{
    public function routeStartup(Zend_Http_Request_Abstract $request)
    {
        // perform your conditional check
        if ($this->_someCondition()){
             $front = Zend_Controller_Front::getInstance();
             $response = $front->getResponse();
             $response->setRedirect('/where/to/go');
        }
    }

    protected function _someCondition()
    {
        // return the result of your check
        return false; // for example
    }

}

Then register your plugin in application/configs/application.ini with:

autoloaderNamespaces[]                        = "My_"
resources.frontController.plugins.conditional = "My_Plugin_ConditionallyRedirect"

Of course, other preferences/requirements for classname prefixing and for file location would entail slightly different steps for autoloading and invocation.
