Computer Blocking CORS OPTIONS Request

This is driving me crazy! I\'m trying to work with Amazon S3 CORS requests and they are not working on my computer. It seems that my computer is blocking or ignoring the OPTIONS

More specifically, the problem seems to be in the Web Security module of AnyConnect. I was able to fix the problem by uninstalling and reinstalling AnyConnect with the Web Security option unchecked; or, just by running the websecurity_uninstall.sh script. (This was with AnyConnect 3.1.04074.)

Thanks to the @user3021922 and others for identifying the issue - this was driving me crazy too.
