Why I'm getting always a new session in SparkJava?

I have a SparkJava api filter that is called by my client every 30 seconds.

before("/app/*", {
    req, _ ->
    println(req.session().attributes().size)
    println(req.session().id())
    println(req.session().isNew)
    req.session().attribute("test", "test")
})

The result is: 

0
node0r3ulllnarwq5i62o2wcpxmu25
true
0
node0i0morm89ftci1tntiu38p8l5026
true
0
node09n12ooeo0t34wkpaqfhbbou227
true

You can see above, the session id is always different. Why the session is always a new session?

Solution

  • I was stupidly mistaken, but the behavior is correct. REST is stateless and has no session.

    There is a good explanation:
    If REST applications are supposed to be stateless, how do you manage sessions?
