Hack http header

The idea is simple. Find right APIs and use them to change or add HTTP header fields for specific purpose.

Like in Android:

            DefaultHttpClient httpClient = new DefaultHttpClient();
            httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "iTunes-AppleTV/5.1 (3; 8GB; dt:12)");
            HttpPost httpPost = new HttpPost(url);
            httpPost.setHeader("X-Apple-Store-Front", "143463-18,18A");
            httpPost.setHeader("X-Apple-TV-Resolution", "1080");
            httpPost.setHeader("X-Apple-TV-Version", "5.1");

            HttpResponse httpResponse = httpClient.execute(httpPost);

The problems lie on Javascript script tag. It's much easier to do this for XMLHttpRequest() because there're some corresponding APIS to use from, but when it comes to script tag, I can't find a solution online for this as to now.
