Ajax重置会话php

I use my own Framework, in localhost all works perfectly fine but not on the server.

I'm logged, so I've a session id.

On a ajax request, the php script doesn't keep my session, if I return the session, the session are empty but me in my side, I keep the session.

It's like if the server thinks the ajax request is a new user.

I don't know where to look and I can't post all the framework code here... Yesterday I already have this issue (at work) then at home, I retested and all worked great...

I don't get it...

$(document).on('click', '.edit', function(){
    $.ajax({
        type: "POST",
        url: ROOT+"list",
        data: {id:id},
        headers: { 
            Accept : "application/json; charset=utf-8"
        },
        cache: false,
        success: function(data){
            console.log(data.sess.ROLE);
            if(data.status == "error"){
                //error
            }else{
                //ok
            }
        }
    });
});

Controller:

public function editAction(){
    //if(!$this->ROLE('tokayn')){ $this->redirectUrl('thread_index'); }

    if(Request::POST()){
        if(is_int($_POST['id'])){
            $user = $this->batiments->findById($_POST['id']);
            if($user->id_proprio == $_SESSION['id']){ 
                $data = array('status'=>'ok', 'message'=>$user);
                Request::renderJson($data);                         
            }else{
                Request::renderJson(array('sess'=>$_SESSION));  
                //$data = array('status'=>'error', 'message'=>'error');
                //Request::renderJson($data);   
            }
        }else{
            $data = array('status'=>'error', 'message'=>'error');
            Request::renderJson($data);     
        }
    }else{  
        //$this->redirectUrl('thread_index');
    }
}

If a user is not logged, the session role is 'visitor' but if he's logged, the session role is 'connected'.

I've a echo before the ajax form and it's 'connected'. Then, on submit the ajax form, the ajax request return 'visitor' but if I refresh, I keep the 'connected' echo...

I've faced this issue for me the problem was I was using

https://server:1234/somecontroller

while i was requesting from ajax as

http://server:3344/somecontroller

and session was not shared between https and http so double check if this apply for you.
