Answer 1

After a lot of digging i found that the page that i'm pinging using ajax is on the internet zone while my current page in on the intranet zone.

IE 11 has the "Protected Mode" enabled for internet sites and when this is enabled cookies are not being sent to the site that i'm pinging even if they belong to that domain.

Adding the page to the trusted sites, or disabling "Protected Mode" solved the problem.

Note that this problem does not happen when both sites are in the internet zone even when "Protected Mode" is enabled.
