AJAX and CI Session (v1.7) w/DB

[eluser]Kobus M[/eluser]
Hi guys,

I have tried EVERY solution mentioned so far. I have spent days on this sofar. I keep getting random session expiration when having Ajax requests. Here is some of what I tried.

1. Replaced Session.php: http://stackoverflow.com/questions/15829...ng-on-webp
2. Tried all variants of this fix that I could find: https://degreesofzero.com/article/fixing...niter.html
3. Everything in this thread: http://ellislab.com/forums/viewthread/102456
4. I tried this: http://www.hiretheworld.com/blog/tech-bl...conditions
5. This: https://github.com/EllisLab/CodeIgniter/pull/1283
6. And this: https://github.com/EllisLab/CodeIgniter/pull/1900
7. Also: http://upshots.org/codeigniter/codeignit...on-bug-fix

I am really at a loss - it is making me grey before my age... :-(

Anybody else with something I can try?

Kind regards,

Kobus
