https://httpd.apache.org/docs/2.4/howto/http2.html#push

i really doubt i did this correctly but i edited templates on includecss to add this because my site is using cloudflare too. 

    <link rel='stylesheet' href='{expression="\IPS\Http\Url::external( $file )->setQueryString( 'v', \IPS\SUITE_UNIQUE_KEY )"}' media='all' rel='preload' as='stylesheet'>

The problem with h2 push is that it can't take account of caching, because you are just sending the data to the client without it asking, but almost all resources that you would serve with a site running IPS are cacheable by the client, so it would actually use more bandwidth and potentially be a bit slower, because most users will have the resources cached.
