I am using apache common httpclient 4.3.3 to make http 1.0 request. Here is how I make the request
HttpClient client = HttpClientBuilder.create().build();

I think you could add your implementation of HttpRequestInterceptor with client.addRequestInterceptor()
or (better)
remove all interceptors that add headers to the request (RequestUserAgent, RequestDefaultHeaders, RequestClientConnControl, RequestAcceptEncoding, ...).
Removing them is also easy:
client.removeRequestInterceptorByClass(RequestAcceptEncoding.class);
