Post data to another website

Hi all,

I am trying to create a new payment plugin for my local provider, now the provider accepts data as post data from the form, how can I post data to the form, I've created a payment processor class like paypalstandardprocessor class, and i am loading data via that, but unable to do so, can you please help me with that.

I am quoting how I achieve that rightnow in my asp.net form


OLD ASP.NET CODE:
System.Web.HttpContext.Current.Response.Write("<form name='frmTransaction' method='post' action='https://secure.ebs.in/pg/ma/sale/pay/'>");
            System.Web.HttpContext.Current.Response.Write("<input name='account_id' type='text' value='****' style='display:none;'  /><input  name='reference_no' type='text' value='" + orderid +"' style='display:none;' /><input style='display:none;'  name='amount' type='text' value='" + amount + "' /><input style='display:none;'  name='description' type='text' value='****' />");
            System.Web.HttpContext.Current.Response.Write("<input name='name' type='text' value='" + name + "' style='display:none;'  /><input name='address' type='text' value='" + address + "' style='display:none;'  /><input name='city' type='text' value='" + city + "' style='display:none;'  /><input name='state' type='text' value='" + state + "' style='display:none;'  />  <input style='display:none;'  name='postal_code' type='text' value='" + postcode + "' />  <input style='display:none;'  name='country' value='" + country + "' />");
            

ASP.NET MVC CODE:
public void PostProcessPayment(PostProcessPaymentRequest postProcessPaymentRequest)
        {
            //nothing
            var builder = new StringBuilder();
            builder.Append("https://secure.ebs.in/pg/ma/sale/pay/");
            builder.Append("");
        }

Not sure how to achieve, this are there are any NOP developers I can use to do this coding for me :)

Any help is appreciated ASAP :)

Thanks
Amit.
