worldpay integration asp.net

Hi I am trying to integrate worldpay on my asp.net website. I have used this code to achieve the integration.

//test environment url
string url = "https://secure-test.worldpay.com/wcc/purchase";

//get all form elements
NameValueCollection formData = new NameValueCollection();
formData["testMode"] = "100";

//all the form fields here

//make the call to submit form data
WebClient webClient = new WebClient();
byte[] responseBytes = webClient.UploadValues(url, "POST", formData);
string response = Encoding.UTF8.GetString(responseBytes);            
inputdiv.Visible = false;
outputdiv.Visible = true;
outputdiv.InnerHtml = response;    

Basically I am getting the response and displaying it on a div. Everything works, but the links are having relative path which shouldn't be the case. Except the image urls, all other urls should point to worldpay. how to achieve this? Any suggestion will be much appreciated.

Please try this, hope this would help a lot.

Html

<form action="/complete" id="paymentForm" method="post">

    <span id="paymentErrors"></span>

    <div class="form-row">
        <label>Name on Card</label>
        <input data-worldpay="name" name="name" type="text" />
    </div>
    <div class="form-row">
        <label>Card Number</label>
        <input data-worldpay="number" size="20" type="text" />
    </div>
    <div class="form-row">
        <label>CVC</label>
        <input data-worldpay="cvc" size="4" type="text" />
    </div>
    <div class="form-row">
        <label>Expiration (MM/YYYY)</label>
        <input data-worldpay="exp-month" size="2" type="text" />
        <label> / </label>
