Hi, i am building a web service with zend and i am using modules to separate my api versions. Ex: "applications/modules/v1/controllers", "applications/modules/v2/controllers" have different set of actions and functionality.

I have made "v1" as the default module in "application.ini" file:

resources.modules = ""
resources.frontController.defaultModule = "v1"
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.frontController.moduleControllerDirectoryName = "controllers"

I have written the following in my bootstrap file:

$router = $front->getRouter();

$r1 = new Zend_Controller_Router_Route_Regex('api/v1/tags.xml',
                array('module' => 'v1', 'controller' => 'tags', 'action' => 'index'));
$router->addRoute('route1', $r1);

Suppose, if this is my url: http://localhost/api/v1/tags.xml

then it belongs to version 1 (v1).

But i dont want to write many routes like this one, so i want to know how can i track the version from the regex url and dynamically determine the api version to be used (1 or 2).
