connslots and frontend/backend controls

I am attempting to limit the number of connections on a per host header basis. Currently each host header has it's own ACL and backend. This allows me to use maxconns and limit the number of connections per host header even if the physical server is the same in both backends. ### frontend

ACLs in TCP mode

I saw a post from October 2007 (http://www.formilux.org/archives/haproxy/0710/0124.html) where it was stated that ACLs weren't supported in TCP mode. Is that still the case? Specifically, I'm looking to use the source IP (src) ACL to route connections to one of several backends. Thanks,

Re: Connection Pooling

Re: Kernel tuning recommendations

I tried to dig deep enough to disable the state module and nf_conntrack and was finally successful. I used the iptables script attached below to get there. I had to modify /etc/sysconfig/iptables-config to remove (comment out) the following line # IPTABLES_MODULES=ip_conntrack_netbios_ns

Re: connslots and frontend/backend controls

Thanks Willy, I appreciate you looking into it. Can you detail how this new verb might work? From your description it sounds like it will be just the total connections to a specific backend? Or will it be more similar to be_sess_rate but for total connections rather than rate? I am looking to do
