Hi, Jiahui I think the HTTP KeepAlive(*1) is enabled on your real servers. *1 http://httpd.apache.org/docs/2.2/en/mod/core.html#keepalive When the "KeepAlive" setting is "On", the url module does not work properly (I believe it behave like you explained). If the "KeepAlive" setting is "Off", please show me your l7directord.cf file.
