Its possible that I'm doing this wrong, I don't see many examples of
working with tcp streams, but this combination seems to SEGV haproxy 1.6
consistently.
The idea is to capture the first 32 bytes of a TCP stream and use it to
make a sticky session. What I've done is this:
frontend fe_capture
mode tcp
bind *:9048
default_backend be_capture
backend be_capture
mode tcp
balance roundrobin
tcp-request inspect-delay 5s
tcp-request content accept
stick-table type binary len 32 size 30k expire 30m
stick on payload(0,32)
server test9050 127.0.0.1:9050 weight 1 check observe layer4
server test9051 127.0.0.1:9051 weight 1 check observe layer4
And to test it I do this:
curl -v http://127.0.0.1:9048/
(And I'm not really doing all this to look at http, this is just an example
that demonstrates the issue)
