This feature is useful for applications experiencing spikes of traffic leading to undesirable queue times, as clients will disconnect (and perhaps even retry, compounding the problem) before unicorn can even start processing the request. To enable this feature, add the following line to a unicorn config file: check_client_connection true This feature only works when nginx (or any other HTTP/1.0+ client) is on the same machine as unicorn. A huge thanks to Tom Burns for implementing and testing this change in production with real traffic (including mitigating an unexpected DoS attack). ref: http://mid.gmane.org/CAK4qKG3rkfVYLyeqEqQyuNEh_nZ8yw0X_cwTxJfJ+TOU+y8F+w@mail.gmail.com This release fixes broken Rainbows! compatibility in 4.5.0pre1. * http://unicorn.bogomips.org/ * mongrel-unicorn@rubyforge.org * git://bogomips.org/unicorn.git * http://unicorn.bogomips.org/NEWS.atom.xml -- Eric Wong _______________________________________________ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
