Hi,
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'}p.p2
{margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; min-height:
14.0px}I have a haproxy(v1.8.14) in front of several nginx backends, everything
works fine until I add compression in haproxy.
My config looks like this:
### Config start #####global maxconn 1000000 daemon nbproc 2
defaults retries 3 option redispatch timeout client 60s timeout
connect 60s timeout server 60s timeout http-request 60s timeout
http-keep-alive 60s
frontend web bind *:8000
mode http default_backend appbackend app mode http #filter
compression #filter trace server nginx01 10.0.3.15:8080### Config end
#####
Lua script used in wrk:a.lua:
local count = 0
request = function() local url = "/?count=" .. count count = count + 1
return wrk.format( 'GET', url )end
01. wrk test against nginx: everything if OK

03. Wrk test against haproxy, add filter compression: read error
Change
#filter compression===> filter compression

04. Wrk test against haproxy, add filter trace, and update flt_trace.c:
static inttrace_attach(struct stream *s, struct filter *filter){ struct
trace_config *conf = FLT_CONF(filter); // add below // ignore this
filter to avoid performance down since there are many print return 0;
And change #filter compression #filter trace===> #filter compression
filter trace

Is there any config error? Am I doing something wrong?
Thanks
