I answered my own question.
What I did was to explicitly send the OPTIONS & GET requests with the correct
header information set rather than following redirects. This allowed the CORS
header to be properly set on the file that was gotten so that other users were
able to get it from cache without issue.
So here is what I did:
* I removed Follow Redirects from the original GET request
* Extracted the Location into 2 variables (URL and the rest of the
location) from that original GET response header
* Added an OPTIONS request with the extracted URL and put the rest of the
location in for the Path – do not Follow Redirects
* Added the following header values to he HTTP Header Manager under the
OPTIONS request
* Access-Control-Request-Method: GET
* Access-Control-Request-Headers: origin
* Origin: https://<BaseURL>
* Added a GET with the same URL and Path as the OPTIONS request and same
header values – do not Follow Redirects
I hope this will help someone else some day.

Subject: CORS Redirect in JMeter
Hello,
I have a CORS-related question: Has anyone found a way to get JMeter to follow
a redirect of a GET request by first sending an OPTIONS request with the
appropriate CORS-related headers (Origin, Access-Control-Request-Headers, and
Access-Control-Request-Method), followed by a GET request to the redirected URL?
It seems that JMeter doesn’t send the proper CORS-related headers on it’s own.
