Hey there, @Jennifer_G
Thanks for following up. This doc states that: Our CDN edge nodes do URL normalization before the redirect rules kick in. This happens to make sure we can guarantee the highest possible cache hit rate and the absolute best performance for your site.
Here is a thread where folks have requested this feature to change. I have opened an issue in GitHub for this as well. Should you wish to add to this request, please do not hesitate to add your reasons for wanting this feature to the thread I linked.
Have a great day
