string url = "3rd Party Url";

StringBuilder postData = new StringBuilder();

postData.Append("first_name=" + HttpUtility.UrlEncode(txtFirstName.Text) + "&");
postData.Append("last_name=" + HttpUtility.UrlEncode(txtLastName.Text));

//ETC for all Form Elements

// Now to Send Data.
StreamWriter writer = null;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";                        
request.ContentLength = postData.ToString().Length;
try
{
    writer = new StreamWriter(request.GetRequestStream());
    writer.Write(postData.ToString());
}
finally
{
    if (writer != null)
        writer.Close();
}

Response.Redirect("NewPage");

i am implementing cashu regarding the same but during response.write it shows the following error: The underlying connection was closed: The connection was closed unexpectedly. also i need to redirect it to the cashu page – Intrauterine

what is "New Page" in this?? – Hydrops

So this solution works going to “NewPage” with parameters. I’m also trying to set session cookie (so logging the user in) in target website but the cookie doesn’t seem to set for some reason. Eg. Site A POST to Site B. Inside Site B I’m trying to set FormsAuthentication cookie. Any ideas? – Gunyah
