It is not elegant to define hundreds of backend.

Hi,
If we have 5 servers within a back-end, how can we specify some request to
certain server based on client ip?
For example:
backend
server s01
server s02
server s03
server s04
server s05
How can we make all requests comes from 217.192.7.* goes to serv
you can try 'use_backend' with ACL.
for example you can config two backends named be1 and be2.
then:
acl a1 path_reg "some_regex1"
acl a2 path_reg "some_regex2"
use_backend be1 if a1
use_backend be2 if a2
if you carefully design the regex1 and regex2, it will work fine.
notice that if be1 is dow
Hi
Here we want haproxy to write logs to separate log files (i.e.
/home/admin/haproxy/var/logs/haproxy_20120131.log), and we want to rotate the
log files. Then cronolog seems to be a good candidate.
We don't want to change /etc/syslog.conf or /etc/syslog-ng.conf, because we

Sorry I can't provide a clean patch, because vgroup is just one of several

I did not consider the rewrite rules at that time. Maybe we can add a function

It would be better if official version can provide this feature.

One another way would be:
Use crontab to start a script, this script can get status of servers by `curl
http://your.haproxy.com:8080/admin_status;cvs`
Then you can send messages to anywhere you like.

I've made a private patch to haproxy (just a few lines of code, but not
elegant), which can support this feature.
My condition is just like your imagination: consistent-hashing to a group then
round-robin in this group.
Our design is that several 'server' will share a physical machine, and 's

In my condition, I set the http-server-close option for client-side keepalive.

My question is will haproxy re-assign backend server for every HTTP request in

Hi Willy,
In the mainpage I saw below: "1.5 will bring keep-alive to the server, but it
will probably make sense only with static servers."
While in the change-log or source code I did not find this feature (server side
keep-alive).
Am I missing something, or server side keep-alive still on go
