CDN Issue -Check x-hw Header

Our website is taking a long time to load even though we have a CDN. We believe our origin is intentionally redirecting (302) any non-www assets to www meaning our custom domain [login to view URL] isn't being used. It seems our CDN domain requests have .p at end of their x-hw response header so they are always proxied to our origin instead of being served from our CDN cache at Stackpath. This explains the long load times. You can test this in GT Metrix (see Waterfall. Website is [login to view URL] If it helps, the attached PDF summarises the key issues raised by Stackpath. I am looking for a Prestashop developer who can resolve this issue.
