Thanks that helps. I tried the same thing and surprisingly I see Http 505 on telnet but not in the logs. I am going directly to the tomcat bypassing BigIP [r...@e1 ~]# telnet ws1 8080 Trying 10.10.50.55... Connected to ws1 (10.10.50.55). Escape character is '^]'. GET / HTTP1.1 HTTP/1.1 505 HTTP Version Not Supported Server: Apache-Coyote/1.1 Date: Thu, 11 Feb 2010 15:42:24 GMT Connection: close Connection closed by foreign host. I had to hit enter twice to get the result. Does it sound ok?
