HTTP OPTIONS method blocked on osx (10.9.2)

Question

I have issue with my mac. I can't send a http options request from my browser or using curl cmd. I don't have a clue why. It's not working for all users on my comp. I turned off the firewall and all unnecessary services but problem is still here.

I've recorded videos showing the problem:

Seems to be related to Cisco AnyConnect. Fixed it for my colleague by reinstalling Cisco AnyConnect with limited security.
