Dear Brenden,

I do it in this way:

1. I set balance to "source"
2. I declare the cookie lines as: "cookie XXXX insert indirect nocache"

Example:

---

listen EXAMPLE 10.20.30.40:80

        mode    http
        cookie  EXAMPLE insert indirect nocache
        balance source
        server  SRV1 10.20.30.41:80 cookie s1 check inter 1200 rise 2 fall
3
        server  SRV2 10.20.30.42:80 cookie s2 check inter 1200 rise 2 fall
3 
        option  abortonclose
        option  httpclose
	source  10.20.30.40
--------------------------------------------

As far as I understand (covered before on the list, unfortunately I do not have the link to the discussion) this method will use cookies to keep the requests to the same server. If the client is not able to keep cookies, then the "balance source" will redirect the client to the same backend server as far as the number of servers remains constant.

best regards,
unai
