> A user has reported that results from a SOAP service using the SOAP-Relational connector are sometimes invalid.  This is due to the results from an earlier invocation being returned.  After further investigation this turned out to be a bug with the web server that was hosting the web service and its inability to properly handle chunked requests.
> By default, Axis 1.3/2 (not sure what we are using lately) uses chunked Transfer-Encoding.  By disabling chunked transfer encoding it allows the faulty web server to properly serve the request and return the expected results.
> Ideally, chunked requests should be used as per the default Axis configuration but we should expose a means of overriding this behaviour in the event a user runs across a buggy web server.
> For example, in SOAPExecutor chunked requests can be enabled/disabled via a setting in the Call properties.
> 		Boolean isChunked = ((HTTPConnectorState) this.getState()).isHttpHeaderTransferEncodingChunked();
> 		if (isChunked != null) {
> 	        Hashtable httpProps = (Hashtable) call.getProperty(HTTPConstants.REQUEST_HEADERS);
> 	        if (httpProps == null) {
> 	        	httpProps = new Hashtable();
> 	        }
> 	        httpProps.put(HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED, isChunked);
> 	        call.setProperty(HTTPConstants.REQUEST_HEADERS, httpProps);
> 		}
>  
> Please note, this code was written against Axis 1.3 which is used in XML-Relational SOAP Connector for MMx 5.5.3.
