HTTP2 Server Push + WOFF2 files



There is a problem that I cannot solve. I successfully set up server push a while ago, but Chrome always gives me this error message:

<link rel=preload> has an unsupported 'type' value

This error relates to WOFF2 files. Chrome would prefer this format for server push

Link: <>; rel=preload; as=font; crossorigin; type='font/woff2'

but this is the one that works with Cloudflare:

Link: <>; rel=preload; as=font; type=font

Is anyone managed to get WOFF2 push work with Cloudflare but without any error messages in Chrome?


A Worker preload recipe from Kenton Varda off of StackOverflow

We’ve been serving CSS and JS assets with excellent results.
Well done Kenton!

"</fonts/css/font.css>; rel=preload; as=style; nopush")

Using the absolute path we got the same error as you did
" has an unsupported ‘type’ value"

We got the idea to help new visitors from this recipe

We have not tried web-fonts.


I was getting those errrors in Chrome also. Iused this code in a web.config file and it worked like a champ.
