Re: anyone doing this: internet - http proxy with KA - haproxy?
I tried the version from git and it worked ok - not sure if the client side has KA running, so it may not help the problem. The throughput was fine and stayed high during the run, but the memory use increase was linear until all RAM was consumed - recompiled again and tried with slice-auto on to see if that would help and same result after about 3 hours, all RAM used.

Anyone doing this? config suggestions? you can simply download the very latest snapshot (not yet available in the snapshot directory, you'll have to extract it from GIT) : http://haproxy.1wt.eu/git?p=haproxy.git;a=snapshot;sf=tgz Then replace option httpclose with option http-server-close and you'll have keep-alive on the client-side. It also supports pipelining, which further reduces latency when your clients support it too. Best regards, Willy
