Ordering HttpClient Headers does not seem possible

It seems impossible to have the HttpClient headers sent "before" the HttpRequest headers.

When inspecting the headers of the actual connection, these headers will appear BEFORE the HttpClient
headers.

For example, note the order the header values are set in the following code:

// Set the User-Agent value for the HttpClient
myHttpParams.setParameter(CoreProtocolPNames.USER_AGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322");

// Set the Accept-Language value for the request
request.addHeader(HttpHeaders.ACCEPT_LANGUAGE, "en-us,en;q=0.5");

// Upon execution, the request will send the headers in the following order

Accept-Language: en-us,en;q=0.5
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
