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?

    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)
