Logged out after too many quick requests

Hi,

I am using Resumable.js to upload very large files to my Laravel App (e.g. 500 Gig files). To do so, Resumable.js slices the file and uploads chunks of 10Mb at a time. This works well from a network / load perspective.

The problem is, after a serie of quick ajax requests from the same page, I get logged out (maybe 25 requests within a few seconds).

I have turned off CSRF but it doesn't change my problem. The only middleware I can see in the route file is 'auth' and I don't see any sort of throttling that could be the problem.
