That looks like it. The config below works with 1.5, but I'm not sure that the health check is actually checking the correct backend. I'll take a look at the server logs to see if the health checks are arriving at the correct place.

Is it correct to put the full URL in the httpchk section, like so? _______________________________ backend foo mode http option forwardfor balance roundrobin option httplog option httpchk https://my.URL.here/ cookie BEserver insert server foo1 192.168.123.123:443 ssl cookie foo1 maxconn 5000 check server foo1 192.168.123.124:443 ssl cookie foo2 maxconn 5000 check _______________________________ It's not clear to me if that will actually check each backend server, or if it will only try to fetch that URL, which may not be the correct backend. Please let me know if I can provide any additional information. Thank you!
