WSO2 ESB FORCE_HTTP_1.0 not working

Question

I'm trying to force the WSO2 to set the http version to 1.0 because the client of a service requires the Content-Length property. I configured the following properties in the outSequence, before the <send/>:

<property name="FORCE_HTTP_1.0" value="true" scope="axis2"/>
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>

but it doesn't works! The response header:

HTTP/1.0 200 OK
userAgent: Synapse-PT-HttpComponents-NIO
Host: localhost:8280
SOAPAction: "sendMessage"
Accept-Encoding: gzip,deflate
Content-Type: text/xml; charset=UTF-8
Server: WSO2-PassThrough-HTTP
Date: Thu, 13 Mar 2014 21:55:25 GMT
Connection: Close

I'm using ESB 4.6.0 and SoapUI to call the service.
Why the Content-Length doesn't appears? What's wrong?

Answer 1

This is a bug in ESB and we fixed it recently.

https://wso2.org/jira/browse/ESBJAVA-2985

The properties you mentioned are not working in outSequence path.

The fix should be available in next release.

The patch for Synapse transport is also attached in ESBJAVA-2985 and you may patch the Synapse version in your WSO2 ESB.
