How to send HTTPS-Post request using C# application??

Hi,

I am trying to access a servlet hosted on Tomcat server using HTTPS
Post protocol. I am getting the exception:
"The underlying connection was closed: Could not establish trust
relationship with remote server".

Below is the code snippet. The same worked fine for HTTP POST. Then
when I configured the Tomcat server ffor HTTPS, and modified the code
by just changing the protocol from http to https. What more is to be
done for HTTPS??
I am not sure where is the gap.

Any help/url is highly appreciated.

string str = "TEST DATA";
string uri =
"https://127.0.0.1:8443/MYLOGINPAGE/AMCWEBLOGINGATEWAY?LOGINID=guest&PASSWD=passwd12";
HttpWebRequest request = (HttpWebRequest)
WebRequest.Create(uri);request.KeepAlive = false;
request.ProtocolVersion=HttpVersion.Version10;
request.Method = "POST";

byte[] postBytes = Encoding.ASCII.GetBytes(str);
request.ContentType = "text";
request.ContentLength = postBytes.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();

HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Console.WriteLine(new
StreamReader(response.GetResponseStream()).ReadToEnd());
Console.WriteLine("Headers:");
Console.WriteLine(response.Headers.ToString());

Is the server certificate good? i.e. when you browse to the site with IE,
does it pop up any warning dialogs like wrong server name, cert expired,
untrusted root, etc?

If so, then you need to read this article:
