Status=vary_header_present

cf-polished: degrade=85, origSize=44481, status=vary_header_present

What is the meaning of “status=vary_header_present”? How do I verify that CF is delivering webp for supported browsers?

I am on the Cloudflare Pro plan and Cloudflare Polish is enabled along with the WebP option.

Here is the full HTTP header for an image file(hosted on the same domain) -

accept-ranges: bytes

alt-svc: h3=":443"; ma=86400, h3-29=":443"; ma=86400, h3-28=":443"; ma=86400, h3-27=":443"; ma=86400
