title: Spring HttpSession on Redis change key name
body: <p>I have my multiservices app that use spring HttpSession on Redis.
  All works fine but I want to know if is there a way to change the key value.
  To understand better, spring stores session data on redis on key "spring:session:......"
  I want to append the name of my app on the head:
  "myappname:spring:session:...."</p>
  
  <p>Someone knows if is it possible?</p>
  
  <p>Thanks</p>
