ingress TCP connection state (2 replies)

Hello,

I have got haproxy installed from CentOS 6 repository, and I use TCP mode for a special messaging protocol. Occasionally, the ingress TCP connection dies, but the TCP connection towards the application server survives. There is a not very short time period when application server thinks that the TCP connection is alive and sends out messages towards the mobile client. However, those messages get never delivered! My configuration is very simple:

defaults
log global
mode http
option httplog
option dontlognull
retries 3
redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000

listen relay
bind 0.0.0.0:2268
mode tcp
server s1 10.85.45.39:2268

Is there a way how to act based on ingress TCP connection state? I am considering to use keepalive in order to detect the connection loss faster. Do you think this is a viable approach?

Thanks for any help,
Miloš
