This is just a quick reminder note for myself on how to get ExtJs working with cross domain Ajax query and Cookie. My server side code is implemented with Php Slim micro framework which I use .htaccess file on the document root directory.
Step 1. Configure Apache
In my document root setting, I enable some settings can be override by .htaccess file.
<Directory /var/www> Options Indexes FollowSymLinks MultiViews # enable the .htaccess rewrites AllowOverride All Require all granted </Directory>
