Note Submitter: Sbastien ---- Feedback : I had a problem on a "modern" app using a JS front (Vue) and a PHP back querying a MySQL DB. All data is retrieved asynchronously via webservices (JS fetch()). Sessions are used to easily manage user authentication : just a session_start() in an included script, some controls about user, and no more attention about session. Multiple fetch() were executed sequentially by the browser with pending status : ws.php?action=getSomething 3s 3s [===] ws.php?action=getSomething2 2s 5s [==] ws.php?action=getSomething3 4s 9s [====] ws.php?action=getSomething4 2s 11s [==] Where I hoped full async : ws.php?action=getSomething 3s 3s [===] ws.php?action=getSomething2 2s 2s [==] ws.php?action=getSomething3 4s 4s [====] ws.php?action=getSomething4 2s 2s [==] Finally, I obtain this 2nd case full async by using session_write_close() in ws.php as soon as I need no more to write to $_SESSION and before executing long SQL queries.
