Preload fonts using LiteSpeed Cache

Hi,

In this thread, it’s mentioned to use:

RewriteCond %{HTTP_COOKIE} !ls_smartpush [NC]
RewriteRule ^.*$ - [ENV=PRELOAD:true]
Header add Link "</path/to/static/source.woff>; rel=preload;as=font;crossorigin=anonymous,</path/to/static/stylesheet.css>; rel=preload;as=style,</path/to/static/javascript.js>; rel=preload;as=script" env=PRELOAD

I’ve done that using:

RewriteCond %{HTTP_COOKIE} !ls_smartpush [NC]
RewriteRule ^.*$ - [ENV=PRELOAD:true]
Header add Link "https://fonts.gstatic.com/s/montserrat/v26/JTUSjIg1_i6t8kCHKm459WRhyzbi.woff2"; rel=preload;as=font;crossorigin=anonymous,

and it works on our staging website, however, the header loads once, flickers, then loads again.

Is there a way to stop that from occurring?

Also, about 3 years ago, you mentioned “Font preload is on our to-do plan”. Any update on this?

Thanks
