Nicely done post about the technical implementations & gotcha’s related to HTTP/2.
HTTP/2 push is more complicated and low-level than I initially thought, but what really caught me off-guard is how inconsistent it is between browsers – I’d assumed it was a done deal & totally ready for production.
This isn’t an “HTTP/2 push is a douchebag” hatchet job – I think HTTP/2 push is really powerful and will improve over time, but I no longer think it’s a silver bullet from a golden gun.
