Use to set GET parameters as bean properties and use to execute a bean action and use NavigationHandler to perform navigation programmatically.

    FacesContext context = FacesContext.getCurrentInstance();
    NavigationHandler navigationHandler = context.getApplication().getNavigationHandler();
    navigationHandler.handleNavigation(context, null, "outcome");
}

Note that, depending on the concrete functional requirement, JSF might not necessarily be the right tool for the job. I'd investigate if you couldn't better use a servlet filter or even a plain servlet for the purpose.
