Laravel：使用execute-on-server而不是重定向

We know that if we use return redirect('some_url'), the server will return 302 thus the client have to request the new url again. This is very low.

So I wonder whether these is a function that works like this: "return execute('some_url')", and the server response is exactly the same as what we get when we visit the some_url.

The more concrete usages: (The execute function is what I want)

public function index(){
    if(Auth::check()){
        return execute('url1');
    }else{
        return execute('url2');
    }
}

I would appreciate it if anyone could give me some advice!
