is not the right fix, then it should be removed from trunk.
Putting it here is a way to revive the discussion
+ *) mod_proxy: Fix flushing of THRESHOLD_MIN_WRITE data while tunneling.
+ BZ 65294
+ trunk patch: n/a
+ 2.4.x patch: http://people.apache.org/~ylavic/patches/pr_65294-v3.patch
+ +1: ylavic,
+ ylavic: 2.4.x only patch because ap_filter_should_yield() and
+ ap_filter_output_pending() are wrappers for mod_proxy (only)
+ there. trunk needs fixing too but differently (I'm on it), nothing
+ that will be backported anyway.
+ See https://lists.apache.org/thread.html/r5453925c5caf4d5d64747ada6e05f828106d548d0b8462525699f145%40%3Cdev.httpd.apache.org%3E
+ for the discussion on this, how RĂ¼diger had foreseen me, and how
+ I did not listen :/
+ (rule of thumb: always listen to him carefully!).
+
+ *) mod_proxy_wstunnel: Add ProxyWebsocketFallbackToProxyHttp to opt-out the
+ fallback to mod_proxy_http for WebSocket upgrade and tunneling.
+ trunk patch: http://svn.apache.org/r1889792
+ http://svn.apache.org/r1889795
+ 2.4.x patch: http://people.apache.org/~ylavic/patches/ProxyWebsocketFallbackToProxyHttp.patch
