Forwarding request to a content page How can I forward a request from module to a content page?

I have got a module that authenticates users; once authenticated, the module should forward the request to a content page or node (not redirecting).

public HttpKernel::forward($controller, array $attributes = array(), array $query = array()) allows to forward the request to a controller. 

How do I forward the request to, for example, http://localhost:8080/techlab/evaluations, where evaluations is a created article?
You return a RedirectResponse() with the path. If you're in a controller, you can use the redirect() method from ControllerBase.
