I am trying to read the authorization header for an HTTP request (because I need to add something to it), but I always get null for the header value. Other headers work fine.

public void testAuth() throws MalformedURLException, IOException{
    URLConnection request = new URL("http://google.com").openConnection();
    request.setRequestProperty("Authorization", "MyHeader");
    request.setRequestProperty("Stackoverflow", "anotherHeader");
    // works fine
    assertEquals("anotherHeader", request.getRequestProperty("Stackoverflow"));
    // Auth header returns null
    assertEquals("MyHeader", request.getRequestProperty("Authorization"));
}

Am I doing something wrong? Is this a "security" feature? Is there a way to make this work with URLConnection, or do I need to use another HTTP client library?
