Thanks for your post!
Based on my test in IE10, the SessionId will be lost when first close the browser and the SessionId will be remained regardless of the browser has been closed or not if get session again for the same request. I think that is the storage
mechanism of browser.
So, I suggest that you could consider use the cookie and set the expiration
time or store the data in the database.
