Just little over a year ago Cloudflare was one of the first – if not the first – to offer us HTTP/2 Server Push. That feature may be the most important performance benefit that HTTP/2 offers, besides concurrent downloads of course.
Sadly, I haven’t been able to use Server Push because it requires setting the
Link header, which is something that S3 doesn’t support. (Nor the computing storage products that Google or Azure have.)
Can Cloudflare allow us to configure Server Push in other ways too? That would make us less dependent on the particular features of our origin server.
In the blog post mentioned above, there was already some speculation about new tools/features:
In the future, we plan to develop new tools to help our users to make more educated decisions in regards to Server Push. Over time, CloudFlare will even be able to predict the best assets to push automatically.
