Hello, I know that with loaded servers, roundrobin in HAproxy (1.4.4) does not evenly distribute, but my servers are currently getting NO traffic (test setup), and roundrobin balancing does
www1,www1,www1,www1,www1,...www2,www2,www2,...,www1...
I'm verifying this by having the script being run on each server cat /etc/HOSTNAME (slackware). I need to have it switch back and forth each time to test some session stuff (stored in shared memcached) but am having trouble getting it to switch between my two web servers on each request.

So basically, I have some different back-ends (I've verified the ACLs are working), with the default option "roundrobin" selected. I've tried removing weights, removing the minconn/maxconn/fullconn attributes for all servers (not just the backend I'm testing), tried removing the ACLs, etc. I've been testing on dev.site.com BTW.
Anyone see a reason why I can't get something like www1,www2,www1,www2,...? Also, this is one of my first questions on here, so please let me know if I left anything needed out of my post.
Thanks!
