Android - Open browser with a url with request headers

Question

I have a specific requirement where I have to fire a url on the browser from my activity. I am able to do this with the following code :

String finalUrl = "http://localhost:7001/display/result.jsp?param=12345";
Intent browserIntent = new Intent(android.content.Intent.ACTION_VIEW,
                        Uri.parse(finalUrl));

Now, I want to invoke result.jsp by passing 'param' as a request header in the request and not as the queryString itself.

Can somebody please advice ?

Thanks a lot in advance

EDIT Even a POST request with the 'param' in the request body should be fine.

EDIT 2 The accepted answer is for the POST request, not for the headers.

The Android Browser support 'viewing' javascript, for example the following code can launch the Browser app to show an alert dialog:

    String finalUrl = "javascript:alert('hello')";
    Intent browserIntent = new Intent(android.content.Intent.ACTION_VIEW,
                            Uri.parse(finalUrl));
    startActivity(browserIntent);

A common trick to do post operation by javascript is that you create a form by javascript and then submit it. So in theory code like below should work (part of the code is copied from this post):

    //String finalUrl = "http://localhost:7001/display/result.jsp?param=12345";
    String finalUrl = "javascript:" + 
        "var to = 'http://localhost:7001/display/result.jsp';" +
        "var p = {param:'12345',param2:'blablabla',param3:'whatever'};"+
        "var myForm = document.createElement('form');" +
        "myForm.method='post' ;" +
        "myForm.action = to;" +
        "for (var k in p) {" +
            "var myInput = document.createElement('input') ;" +
            "myInput.setAttribute('type', 'text');" +
            "myInput.setAttribute('name', k) ;" +
            "myInput.setAttribute('value', p[k]);" +
            "myForm.appendChild(myInput) ;" +
        "}" +
        "document.body.appendChild(myForm) ;" +
        "myForm.submit() ;" +
        "document.body.removeChild(myForm) ;";
    Intent browserIntent = new Intent(android.content.Intent.ACTION_VIEW,
                            Uri.parse(finalUrl));
    startActivity(browserIntent);
