Thank you. I've adjusted our policies based on your information and it appears to have fixed the issues. The policy now has 2 rules, that look like the following.

 

Rule 1:

Conditions:

HTTP Header full string named 'Cache-Control' does not exist at response time.

Actions:

Insert HTTP Header named 'Cache-Control' with value 'no-cache, no-store, must-revalidate' at response time.

 

Rule 2:

Conditions:

HTTP Header full string named 'Cache-Control' exists at response time.

Actions:

Replace HTTP Header named 'Cache-Control' with value 'no-cache, no-store, must-revalidate' at response time
