/**

 * Example to handle the HTTP-Request send from the ServiceWorker to 

 * subscribe our notification service.

 * 

 * For easy setup we use the SQLite dataprovider and set the database file

 * located in the same directory as this script.

 * You may use the MySQL dataprovider, just locate the database in a differnet

 * directory or write your own dataprovider for your project.

 * 

 * Remember to adjust the path and name of the script in the service worker

 * (PNServiceWorker.js) when implementing the requesthandler in your own project.

 * 

 * Set $bSendWelcome=true, to send a welcome notification to each user 

 * newly subscribed our service, after the subscription was saved in 

 * the database.
