Question

I want to change default Connection:keep-alive from rpc service to Connection:close
What Im doing is:

reqBuilder = new RpcRequestBuilder() {
  @Override
  protected RequestBuilder doCreate(String serviceEntryPoint) {
    RequestBuilder rb = super.doCreate(serviceEntryPoint);
    rb.setHeader("Connection", "close");
    return rb;
  }
};

((ServiceDefTarget) ObjectService).setRpcRequestBuilder(reqBuilder);

But. The default Connection:keep-alive is still appearing. (some gwt class is overriding it)
Any Idea?

The Connection header is managed by the browser. The setHeader is a no-op for this header: http://dvcs.w3.org/hg/xhr/raw-file/tip/Overview.html#the-setrequestheader-method
