Hi, I have Apache 2.2 installed (on Unix), and I am using mod_jk for load balancing between application server instances. I have configured httpd_VHostSSL.conf to redirect requests which come to the webserver. Additionally, using mod_jk and workers.properties, I am load balancing the requests between the application servers. When I start the apache servers, they get started successfully w/o any issues, But when I connect to the application from the browser, the mod_jk logs show that the webserver is unable to connect to the app-server instance. Following is the error message I am getting from logs: [Tue Jan 13 00:19:40 2009] [69898:0000] [debug] jk_open_socket::jk_connect.c (335): socket TCP_NODELAY set to On [Tue Jan 13 00:19:40 2009] [69898:0000] [debug] jk_open_socket::jk_connect.c (433): trying to connect socket 9 to xx.xx.xx.xx:40593 [Tue Jan 13 00:19:40 2009] [69898:0000] [debug] jk_open_socket::jk_connect.c (459): socket 9 connected to xx.xx.xx.xx:40593 [Tue Jan 13 00:19:40 2009] [69898:0000] [debug] ajp_connect_to_endpoint::jk_ajp_common.c (850): Connected socket 9 to (xx.xx.xx.xx:40593) [Tue Jan 13 00:19:40 2009] [69898:0000] [debug] ajp_connection_tcp_send_message::jk_ajp_common.c (896): sending to ajp13 pos=4 len=5 max=16 [Tue Jan 13 00:19:40 2009] [69898:0000] [debug] ajp_connection_tcp_send_message::jk_ajp_common.c (896): 0000 12 34 00 01 0A 00 00 00 00 00 00 00 00 00 00 00 - .4..............

Both the apache server and tomcat server are in the same subnet, and hence there is no issue of ACLs etc.. Any help would be greatly appreciated.
