Chrome正在请求Laravel页面作为ajax请求而不是页面请求

Question

My app loads a laravel page and then I use Vue js to request some additional info on certain pages for. In my laravel methods I use

if($request->ajax()){
    return response()->json([])//json array
}
return view()//my view

However on google chrome when I go to a new page, and then press back to load the last page (or Forward), I am sent the Json response from laravel

Does anyone know why this is happening and how to prevent it?

It works fine on Firefox and Epiphany
