Work Description: Github user masaori335 commented on the issue:
https://github.com/apache/trafficserver/pull/830
Yes, we don't have to follow it, but we should follow it as much as
possible. Because it could be happen that images are sent before CSS/JS, if we
don't follow it.
How about use SETTINGS_MAX_CONCURRENT_STREAMS as the max depth? It looks
appropriate and we don't need new configures.
I'm seeing that with latest Chrome ( 51.0.2704.106 ). Chrome had that bug
in Feb and reverted the changes. IIUC, the bug is about the order of streams
not depth of streams. Now (maybe from Jun), it looks like they fixed the order
and rolled it out.
