laravelでリダイレクトを設定するにはどのような方法がありますか?

Route::get('itsolutionstuff/tags', 'HomeController@tags');

public function home()
{
    return redirect('itsolutionstuff/tags');
}

public function home()
{
    return back();
}
//或者
public function home2()
{
    return redirect()->back();
}

Route::get('itsolutionstuff/tags', array('as'=> 'itsolutionstuff.tags', 'uses' => 'HomeController@tags'));

public function home()
{
    return redirect()->route('itsolutionstuff.tags');
}

Route::get('itsolutionstuff/tag/{id}', array('as'=> 'itsolutionstuff.tag', 'uses' => 'HomeController@tags'));

public function home()
{
    return redirect()->route('itsolutionstuff.tag',['id'=>17]);
}

public function home()
{
    return redirect()->action('HomeController@home');
}

public function home()
{
    return redirect()->action('App\Http\Controllers\HomeController@home',['id'=>17]);
}

public function home()
{
    return redirect('home')->with('message', 'Welcome to PHP.cn!');
}
