How can I redirect page in jsf Handler

using any Interface/Class like FacesContext or HttpServletRequest / HttpServletResponse etc.... ?

My application default project is :below

____________________________________________

http://localhost:8080/dummyPrj/

-----------------------------------------------------------------------------

Now default path with jsf is 

log/logIn.jsf

http://localhost:8080/dummyPrj/log/logIn.jsf

After successfull login set to

home/homeView.jsf

http://localhost:8080/dummyPrj/home/homeView.jsf

now I want to redirect from here to log/logIn.jsf

http://localhost:8080/dummyPrj/log/logIn.jsf
