title: How to share session between php app and Java EE app?
body: <p>We may replace a PHP app with a Java EE app, but the problem is we wanna replace the modules one by one, which means two apps would co-exist and communicate with each other.</p>
  
  <p>So is it possible to share the user session between the 2 apps? Or use a cookie to solve the problem?</p>
