php - Start a session in read-only mode -

my problem following:

i have page runs series of ajax calls e.g.

$.ajax({ url: "/user/post1" }); $.ajax({ url: "/user/post2" }); $.ajax({ url: "/user/post3" }); ... $.ajax({ url: "/user/postn" });  

(i've determined ids beforehand)

i've got:

$.ajax({ url: "/user/modifysessiondata" });  

now problem need start session in each , every request (to current user) , in addition "/user/modifysessiondata" needs modify session data.

however i've noticed if execute ajax requests @ once it's possible if /user/postx request starts before /user/modifysessiondata request , ends after save session data when request called , therefore overwrite session data set 2nd call.

my question is:

is possible flag session started in specific request "read only"? need create new custom startsession middleware this?

am doing ridiculous?

note: clarify i'm talking laravel session. using redis backed session storage.

in case helps ended doing:

in routeserviceprovider.php boot() method:

route::group([     'middleware' => 'readonly',     'namespace' => $this->namespace, ], function ($router) {     route::get("user/{post}","usercontroller@getpost"); }); 

in kernel.php:

'readonly' => [                     \app\http\middleware\encryptcookies::class,         \illuminate\cookie\middleware\addqueuedcookiestoresponse::class,         \app\http\middleware\startreadonlysession::class,                     \illuminate\view\middleware\shareerrorsfromsession::class,         \app\http\middleware\verifycsrftoken::class,            'bindings',  ] 

this copied web route group exception of startsession swapped startreadonlysession

here's startreadonlysession code (the punchline of issue):

use illuminate\session\middleware\startsession; class startreadonlysession extends startsession {     public function terminate($request, $response) { /* nothing */ } } 

this starts session not save when request terminates. else behaves identically.
