Sending HTTPS from a PDA

Hi there,

I am using the following code to send via HTTP but I would rather send via HTTPS, if i change the http to https it crashes. Any healp would be wonderful..

// Create a new 'HttpWebRequest' object to the mentioned Uri.
                              HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://xxx.xxx.xxx.xx/cgi-bin/pda/inbound");
                                                            myHttpWebRequest.AllowWriteStreamBuffering = false;

                              string postData = fileLine;

                              // Set 'Method' property of 'HttpWebRequest' class to POST.
                              myHttpWebRequest.Method = "POST";

                              ASCIIEncoding encodedData = new ASCIIEncoding();

                              byte[] byteArray=encodedData.GetBytes(postData);

                              // Set 'ContentType' property of the 'HttpWebRequest' class to "application/x-www-form-urlencoded".
                              myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";

                              // If the AllowWriteStreamBuffering property of HttpWebRequest is set to false,the contentlength has to be set to length of data to be posted else Exception(411) is raised.
                              myHttpWebRequest.ContentLength = byteArray.Length;

                              Stream newStream=myHttpWebRequest.GetRequestStream();

                              newStream.Write(byteArray,0,byteArray.Length);

                              newStream.Close();

                              // Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
                              HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

Thanks for the suggestion. I implemented your change but unfortunately I am still receiving the same error. System.net.WebException : The remote name could not be resolved.

When i try and access the cgi through a browser it works fine, no cert messages, just the standard "No document received."

But the exception changed. It used to be: "Could not establish trust relationship with remote server" and now it's "The remote name could not be resolved". Do you have access from the pda to the site? and what do you mean with "the standard no document recieved"? is the target page expecting something?

myHttpWebRequest.AllowWriteStreamBuffering = false;

myHttpWebRequest.KeepAlive = false;

string postData = fileLine;

Set 'Method' property of 'HttpWebRequest' class to POST.
myHttpWebRequest.Method = "POST";

ASCIIEncoding encodedData = new ASCIIEncoding();

byte[] byteArray=encodedData.GetBytes(postData);

// Set 'ContentType' property of the 'HttpWebRequest' class to "application/x-www-form-urlencoded".

myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";

myHttpWebRequest.ContentLength = byteArray.Length;

Stream newStream=myHttpWebRequest.GetRequestStream();

newStream.Write(byteArray,0,byteArray.Length);

newStream.Close();

// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

myHttpWebResponse.Close();
