CXF 2.3.2 and gZip Issues

[Alex]

I am using CXF 2.3.2 and I use Soap Handlers to transmit messages. I am
trying to set/request gZip in HTTP REQUEST HEADERS inside my Java CXF WS
Client BUT for some reason its being IGNORED. I don't see gzip being passed
in HTTP REQUEST HEADER and that's why I don't get back gZipped response.
Here is how I am trying to set. What am I missing?

public class LoggerXML implements SOAPHandler<SOAPMessageContext> {
        private String uniqueIdentifier;
        private String sessionId;
        
        public LoggerXML(String sessionId, String uniqueIdentifier) {
                this.sessionId = sessionId;
                this.uniqueIdentifier = uniqueIdentifier;
        }
    
        protected final void setLogStream(PrintStream ps) {
          //  out = ps;
        }
    
        public void init(Map c) {
            uniqueIdentifier = "";
        }
    
        public Set<QName> getHeaders() {
            return null;
        }
    
        public boolean handleMessage(SOAPMessageContext smc) {
            
            Boolean outboundProperty = (Boolean)
            smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
            if(outboundProperty){
                // Creating HTTP headers & setting gZip.
                Map<String, List&lt;String>> headers = (Map<String, 
                                                                
List&lt;String>>)
smc.get(MessageContext.HTTP_REQUEST_HEADERS);
                if(headers == null){
                        //System.out.println("LoggerXML.handleMessage: headers =
null");
                        headers = new HashMap<String, List&lt;String>>();       
                }
                // Add HTTP headers to the web service request
                headers.put("Accept-Encoding",
Collections.singletonList("gzip,deflate"));
                //headers.put("Content-Encoding",
Collections.singletonList("gzip"));
                //headers.put("Accept-Encoding",
Collections.singletonList("gzip"));
                
                smc.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
               
//smc.put("org.apache.cxf.transport.common.gzip.GZIPOutInterceptor.UseGzip","YES");
                
            }
            
            return true;
        }
    
        public boolean handleFault(SOAPMessageContext smc) {
            return true;
        }
    
        // nothing to clean up
        public void close(MessageContext messageContext) {
        }
    
        // nothing to clean up
        public void destroy() {
        }
    
    // Other Methods....
    
    }
