system.net.webexception

I have a web service which is returning data to the desktop application. The problem I am having is, when the web service returns small volume of data everything works fine but when the volume of data is large it throws the following exception: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. And when I am debugging the web service, I see that this particular method is called twice. It executes the return statement 1st time nothing happens, but when it does execute it for the second time the above mentioned exception is thrown in the

For some reason beyond my understanding requests made to a perticular website ( https://learningnetwork.cisco.com/people/mrollins?view=profile ) result in a reqsponse-object whose responsestream contain a trunkated version of the website. The stream ends after 65536 bytes, which equals 2^16 bytes. I consider that a suspiciously round number. The requests complains of an internal server error, which I surpress, because I have already verified both that webbrowsers are able to make sense of this response, and that the full html is included in the response from the server. (using fiddler ) I've

I am trying to use a WebClient / HttpWebRequest to download some data from a server. I use the following code to do so: WebClient client = new WebClient(); client.Credentials = new NetworkCredential("admin", "password"); Stream datastream = client.OpenRead("http://routerlogin.com/cgi-bin/CF_logs.html"); StreamReader reader = new StreamReader(datastream); The server is my page is in my router's configuration. It works fine from a browser, but when downloaded using my code it throws a WebException with the message The server committed a protocol violation. Section=ResponseHeader Detail=CR must

I'm communicating with a web server from .Net. The web server throws a 500 internal server error and writes a detailed error message. I'm trying to read the error message that is received from a web exception, but getting another web exception. Why is the second WebException thrown? try { var webResponse = (HttpWebResponse)webRequest.GetResponse(); } catch (WebException e) { if (e.Status == WebExceptionStatus.ProtocolError) { // the next line throws a web exception Console.WriteLine(new StreamReader(e.Response.GetResponseStream()).ReadToEnd()); } } Why is this surprising? Try the following

I am trying to upload files to a web server using System.Net.WebClient.UploadFile but I keep getting a WebException. Specifically, I am getting 3 errors. I have no idea why I am not getting the same error, but they all seem to be related based on what I found online. The request was aborted: The request was canceled. Connection closed. Try again. An existing connection was forcibly closed by the remote host. It seems somewhat random (not always the same file, amount of time, or any other pattern that I can figure out). Also This doesn't happen on my work network (the uploads take less than 2

I have the following snippet in classic ASP, to send a command and retrieve the response over SSL: Dim xmlHTTP Set xmlHTTP = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0") xmlHTTP.open "POST", "https://www.example.com", False xmlHTTP.setRequestHeader "Content-Type","application/x-www-form-urlencoded" xmlHTTP.setRequestHeader "Content-Length", Len(postData) xmlHTTP.Send postData If xmlHTTP.status = 200 And Len(message) > 0 And Not Err Then Print xmlHTTP.responseText End If Then I used this code as a reference to reimplement the request in c#: private static string SendRequest(string url,

I'm getting this error on just one server running Windows Server 2003: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. Here's my code... Any ideas? HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https:// URL HERE "); //request.Headers.Add("Accept", "application/xml"); byte[] bytes; bytes = System.Text.Encoding.ASCII.GetBytes(xml); request.KeepAlive = false; request.Accept = "application/xml"; request.ContentType = "application/xml; charset='UTF-8'"; request.ContentLength = bytes.Length; request.Method = "POST"; request.Timeout
