When we want to add newsletter feature to our Drupal website, we might end up finding the simplenews module as the solution. But, there is one problem that so many people asked about in the internet.

The Hyper Text Transfer Protocol is a stateless protocol. That means server just forget about you when your request is served and the connection between server and client is immediately closed after that. For example, when you made a request for page a.html, the server send you the a.html. After that, you made second request for b.html. In that time, the server won't recognize that you are the one who previously request a.html.

For example, we have a routing file, mydemo.routing.yml like the following.

All of the system initialization files are located at /etc/rc.d folder. When we want to enable a certain system service to start automatically, we just need to change the file mode into executable. For example, the Apache web server init file is rc.httpd.
