Laravel 5.1 logs out when firing multiple ajax requests

My Laravel 5.1 installation keeps logging out randomly when I fire multiple ajax requests. This is solved by using Redis as session driver, but since this installation is running on Xampp (Windows) I can't use that. I already tried to switch to database session driver but that did not sove the issue.

I'm running PHP5.6.

Any help is appreciated.
