Perfect, thank you William! I've just added a small paragraph to the doc mentioning the impact of using this for those with long idle connections, and pointers to the relevant options timeout client, timeout http-request and hard-stop-after. I could also have added timeout http-keep-alive by the way. Regardless all of them are cross-references, that should be enough. Now merged, thank you! Willy
