HTTP 1.1 Not Supported?

[orbwave]

Our production guys recently reported that their load balancer was not properly moving requests between our servers and it was discovered that when it was pinging the web server, the following reponse was received:

HTTP/1.1 505 HTTP Version Not Supported
Date: Wed, 30 Nov 2005 15:25:02 GMT
Server: Apache-Coyote/1.1
Connection: close

I have verified that I also get this reponse from my local development machine by connecting via telnet and requesting GET / HTTP/1.1

We're running JBoss 4.0.1 SP1

In the logs, I see messages such as...

INFO 2005-11-30 10:24:09,791 [org.apache.coyote.http11.Http11Protocol] Initializing Coyote HTTP/1.1 on http-0.0.0.0-80

So I simply assumed that HTTP/1.1 was supported. Is this not the case?

HTTP 1.1 is supported.

I doubt your talking to a jboss-4.0.1SP1 instance given the lack of the X-Powered-By shown above.
