Default HAProxy IP vs. host routing

I have followed the high availability/load balancer tutorial, works like a charm thanks!

Problem is that I have several vhost on the backend server and HAproxy always routes to the default (in my case first) one.

On the load balancers I have in etc/hots

http1.example.com # where192.168.0.102 is the server with mutiple vhost

I have tried in HAPROXY.cfg

server webA http1.example.com:80 cookie A check

But it still routes me to the wrong vhost (as if it was routing directly to and not to http1.example.com)

Any idea?

I suggest you use Perlbal instead - it supports vhosts.

Thanks for the prompt reply falko. Actually I solved the problem by thinking about it a bit longer

Essentially HAProxy balances nodes only (regardless of domain) so I ended up putting the same vhost on node 1 and node 2!

My HAProxy conf is as per your tutorial and on node1/node2 I have the same

<VirtualHost *:80>
ServerName http.ndd.com

Instead of having previously http1.ndd.com on node1 and http2.ndd.com on node 2 (which btw is the setting one should use when using apache mode_balancer)
