Heads up to Zscaler and Safari 11 users

This is just meant as a heads up to the other people using Zscaler and Safari.
I was seeing problems with websites not loading, content on websites not loading, and general layout issues on websites.
All worked without issues as soon as Zscaler was out of the equation.

Turns out it was caused by the "Prevent cross-site tracking setting":

As soon as that was unchecked, everything started to act normal.
The setting caused Zscaler authentication to get stuck on redirection to the Zscaler gateway.

Hope I can save a fellow admin the headache I had because of this.

Good weekend to all.

Is there a script we can run with Jamf to make sure the setting is correct?

I haven't figured out that part yet, but if someone does, I would be very interested to know how.

Did anyone figure out if this preferences can be set via a JAMF policy?

disabling "Prevent cross-site tracking setting" fixed the issue on my MacOS. However I need to push this change globally to all MacOS.
Is there any sample script that we can run from Jamf to disable "Prevent cross-site tracking setting"?
