Accessing a web service through mod_jk results in chunked encoding

Issue

• A JSON web service deployed on a 2 node cluster.
• When accessing the JSON web service through EWS the server is stripping out the content-length in the response header and the browser (Firefox, IE, Chrome) is not able to render the content.
• This is the response header output from Fiddler when accessing the web service directly:

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
X-Powered-By: Servlet 2.5; JBoss-5.0/JBossWeb-2.1
Date: Tue, 09 Aug 2011 14:19:01 GMT
Content-Type: application/json
Content-Length: 67397 

• This is the response header output from Fiddler when accessing the web service through EWS:

HTTP/1.1 200 OK
Date: Tue, 09 Aug 2011 14:19:02 GMT
Server: Apache/2.2.14 (Red Hat)
X-Powered-By: Servlet 2.5; JBoss-5.0/JBossWeb-2.1
Transfer-Encoding: chunked
Keep-Alive: timeout=10, max=100
Connection: Keep-Alive
Content-Type: application/json
X-Pad: avoid browser bug
