Hello,
Please help me understand this output in the haproxy log file:
Oct 21 14:53:17 host haproxy[4526]: 206.x.x.x:56480
[21/Oct/2014:14:53:16.560] http-in~ servers/server1 60/0/0/527/587 200
243 - - LRVN 12/12/1/2/0 0/0 "POST /ctx/cometd/connect HTTP/1.1"
The first two letters of the termination state are confusing me.
"L" indicates the session was processed by haproxy and not sent to a server
"R" proxy was waiting for a complete request from the client
It also shows a status code of 200.
What circumstances could cause this? I'm testing haproxy now and it
(and the 2 servers behind it) are under no real load. So far I have
only observed this with Chrome Version 38.0.2125.104 (64-bit) linux. I
do not see any errors in the Chrome Network panel and the application
appears to work correctly.
Any insight greatly appreciated.
From a quick test I made, I think you have some redirect rules in your
haroxy configuration.
And it appears that flags are not reset on a keep-alived connection.
Please check in your logs if a previous request already used port 56480
with a 302 status.
This is maybe a bug, but I won't have time tonight to investigate more.
To reproduce it, I used this minimal configuration :
listen testflag :9000
mode http
option httplog
log /dev/log local7 debug err
http-request redirect location /redirected if { path / }
server s localhost:80
$ curl -L http://localhost:9000/

[21/Oct/2014:22:53:40.094] testflag testflag/<NOSRV> 0/-1/-1/-1/0 302 89
- - LR-- 1/1/0/0/3 0/0 "GET / HTTP/1.1"
Oct 21 22:53:40 asus haproxy[11282]: 127.0.0.1:33985
[21/Oct/2014:22:53:40.094] testflag testflag/s 0/0/1/2/3 404 550 - -
LR-- 1/1/0/1/0 0/0 "GET /redirected HTTP/1.1"
Here, the second request inherits LR from the first one.
The same test with curl using HTTP/1.0 :
$ curl -0 -L http://localhost:9000/

---- 0/0/0/0/0 0/0 "GET /redirected HTTP/1.0"
Here, it's OK.
