A friend of mine told me that whenever the image controller calls a new image the session regenerate again. No matter if it's the same page. If the same page has 12 images then that page generates 1 session for the page and 12 sessions for the images almost simultaneously. Curiously this did not happen in CI3 using the Session_native driver so it must be something with the CI3-RC2 session improvements.
Some thoughts about this please?
