Direct access to controller I'm trying to create a plugin with a controller, but I don't want to render any view but run a script from a cronjob. I can't get into the controller with an url and I'm not sure why. 

I already tried everything here but it does not state any way to directly call a controller with an url. Is this possible?
The docs explain how to generate links to controller actions. Assuming your action trigger is "actions" (as it is by default) then your URL will look as follows:

http://www.domain.com/actions/pluginName/controllerName/actionName


Following the first example in the docs, the URL will look as follows:

http://www.domain.com/actions/cocktailRecipes/ingredients/deleteIngredient


Be sure to allow anonymous access to your controller action so it can be reached by the cron job.
