title: HAProxy and "sharding"
body: <p>I was wondering if anyone has used HAProxy for sharding.
  Specifically, I would like to be able use a cookie I define w/a identifier and have any client that presents that cookie/identifier combination be directed to the same server. It seems possible and my preliminary tests seem to work but I am not a sure.</p>
  
  <p>My listen configuration looks like:</p>
  
  <pre><code>listen  appli1-rewrite 0.0.0.0:80
  cookie  mysession= prefix
  balance roundrobin
  server  app1_1 192.168.0.1:80 cookie server01
  server  app1_2 192.168.0.2:80 cookie server02
  
  option  httpclose
  </code></pre>
  
  <p>However, when I look at the request headers using Live Http Headers I don't see the mysession cookie indicating which server it will be going to, which is what I expected based on the prefix operation.
  I am quite new to HAProxy so any help/guidance would be great!</p>
