estamos usando o proxy reverso do Apache e vemos o vs config

ProxyTimeout 1800
ProxyPreserveHost On
ProxyPass           /  http://192.168.10.20/ connectiontimeout=1800 timeout=1800
ProxyPassReverse    /  http://192.168.10.20/

proxy-initial-not-pooled If this variable is set, no pooled connection will be reused if the client request is the initial request on the frontend connection. This avoids the "proxy: error reading status line from remote server" error message caused by the race condition that the backend server closed the pooled connection after the connection check by the proxy and before data sent by the proxy reached the backend. It has to be kept in mind that setting this variable downgrades performance, especially with HTTP/1.0 clients.
