Hi! I add h2c to my protocol configuration. It comes to "Protocols h2 h2c http/1.1". Nevertheless, Apache still disabled my origin server push stream. It seems that Apache never put this into production. PUSH PROMISE STREAM is one of the most important characteristics of http/2 defined in RFC. So, I wonder what is the reason behind. Maybe there is no std library to use? I would be quite grateful if you let me know the considerations

We came to the conclusion (as did chrome who dropped it last year <https://chromestatus.com/feature/6302414934114304>) that client cache and push were probably not compatible with latency, but YMMV.
