5.2: #.#.#

PHP version: 5.6.30 Database Driver & Version: 5.1.73 Description:

|I used Laravel 5.2 version, I noticed that my website user Auth session lost when I used multi requests in great speed, Laravel saves the sessions in storage framework. the problem is maybe because the Laravel recreate another session file in the storage.

note 1: sometimes when I use google chrom button I get the same problem. note 2: my website get another old session when I use back google chrom button note 3: the problem is not fixed the questions:

1- Why Laravel create new Sessoin file and why don't delete the old one?

2- Why Laravel lost Auth Session?

3- Why laravel get another old user session (huge problem)
