Thread safe http request headers?

[Warren, Jared S]

I need to include a unique value in an http header field for each request from 
my CXF client to the web service provider.

It's my understanding that I can do this when I initialize a port:

            ServiceControllerAdapter svc = 
adapter.getServiceControllerAdapter();
            Client client = ClientProxy.getClient(svc);
            client.getRequestContext().put("thread.local.request.context", 
"true");

Then I can use an object pool to pool the adapters, and do something like this 
each time I need one with unique headers:

            ServiceControllerAdapter port = (ServiceControllerAdapter) 
portPool.borrowObject();

            Map<String, List<String>> headers = new HashMap<String, 
List<String>>();
            List<String> mdcIdList = new LinkedList<String>();

            String mdcId = this.getUniqueId();
            mdcIdList.add(mdcId);
            headers.put("MDCID", mdcIdList);

            Client client = ClientProxy.getClient(port);
            
client.getRequestContext().put(org.apache.cxf.message.Message.PROTOCOL_HEADERS, 
headers);

            response = port.process(request);

            
client.getRequestContext().put(org.apache.cxf.message.Message.PROTOCOL_HEADERS, 
Collections.EMPTY_MAP);

            portPool.returnObject(port);


(Note: for reasons beyond the scope of this note, I'm stuck on Apache CXF 
2.2.10.)

Can anyone validate that this should work?

Thanks!
