Hey Michele.
I'm confused as to how "show stat" is correct...

But your script does not correspond to this even though it uses "show
stat"...

Thanks, Carlo. It works.
But can it be simpler? such as:
frontend http
bind :80
mode http
default_backend pool
backend pool
server s01 2.3.4.1:80
server s02 2.3.4.2:80
server s03 2.3.4.3:80

We have many servers for different developers, the rul

Hello all.
I'm try to write custom check my MsSQL servers. Now I can check they by
network ip and port. But maybe situation, then same MsSQL server is alive,
but database is down.
So, I add my check in proxy.h, cfgparse.c, and checks.c in event_srv_chk_r.
After compile HAProxy is started, but my c
Hi guys,
I want to use HAproxy as a LB to my HTTP API, but I want to balance
requests based on some route_id provided either in cookie or in URI
(flash apps cannot set headers in requests). It looks that only
appsession supports reading URI,. Is there any way to do this with
cookie option? Or how

I apologize if I wasn't clear. The comment in my previous email means that the

In other words, disabling servers seems to work fine ALL the times, while

Hello Willy,
when the 'enable' command fails, it ignores ALL the servers in the list, e.g.,
see line 2 and line 4 of the logs below. The command is exactly the same,
however it fails at the first attempt.
For testing purposes, I have now added a small sleep (40 ms) between the
enable/disable c

I think the most useful thing you can do is to provide a socat

Hi,
I'm currently working on HAProxy's health check: reordering and
updating the documentation, renaming some checks and adding new onses
(IMAP and POP for now).
You have to update 2 files, cfgparse.c and checks.c.
The best is to look a t the code for smtpchk, for example, and to try
