setting $_SESSION (php) with remote server using angularJS code not working

Hi I solved the problem finally this way:

Client side, in angularJS I put this in my route-config to apply for all request to ReST-API

$httpProvider.defaults.withCredentials = true;

I think I should have mainly use in .htaccess for web server:

Header add Access-Control-Allow-Credentials "true"

but for your attention, I updated finally the whole .htaccess file to the following:

Header add Access-Control-Allow-Origin "http://localhost:3000"
Header add Access-Control-Allow-Credentials "true"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "GET, POST"
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
<FilesMatch "\.php$">
Order Allow,Deny
Deny from all
</FilesMatch>
<FilesMatch "index[0-9]?\.php$">
Order Allow,Deny
Allow from all
</FilesMatch>

also I use the following for JSON response in php: $response="desired JSON response OBJECT"; $status='OK or unauthenticated or ...' ; $status='200 or 403 or ...'; header("Content-Type:application/json"); header("HTTP/1.1 $status $status_message"); echo json_encode($response); exit();

Hope this question and answer helps you
