Unable to write data to remote HTTPS server

Hi All,
I am getting lot of
System.IO.IOExc eption: Unable to write data to the transport
connection.
exceptions when I write to a Stream which is connected to a Remote
HTTPS server using a proxy and a certificate.

ASCIIEncoding encoding = new ASCIIEncoding() ;
byte[] data = encoding.GetByt es(..........);

HttpWebRequest req = (HttpWebRequest ) WebRequest.Crea te(m_url);
req.Method = "POST";
req.ContentType = "applicatio n/x-www-form-urlencoded";
req.ContentLeng th = data.Length;
req.Proxy = new WebProxy( ...........);
req.Credentials = new NetworkCredenti al(..........);
req.ClientCerti ficates.Add(... .....);

Stream reqStream = req.GetRequestS tream();
reqStream.Write (data, 0, data.Length); // THROWS IOException here

The exception is thrown in almost 50% of the write request throughout
the day. Here is the exception I get.

System.IO.IOExc eption: Unable to write data to the transport
connection.

I fixed it by adding a line of code.

System.Net.Serv icePointManager .Expect100Conti nue = false;

For details, see the link

Hi All, I am new to web service client development. Grateful, if anybody can help me to solve this issue. Or let me know where/what I have done wrong.

I'm trying to send data to a remote script (a credit card processing third party) from my site using POST. Currently, I'm doing it using the ususal form dynamically built with my values. This is less than ideal because I want to perform local processing (updating order status in the local database) and then to proceed to the remote script, with resultant values, without relying on the user pressing a button.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
