We migrated code from vb to vb.net. In vb msxml was used to make http requests and in .net we changed to httpwebrequest. With this new implementation an exception is thrown while executing httpwebrequest.getrequeststream.

The exception code is 10060 and the exception message is A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

This exception occurs intermittently and not always.

Please find below the code snippet which i've used to achieve the result

Dim HttpRequest As HttpWebRequest

Dim HttpResponse As HttpWebResponse

Dim streamReader As StreamReader

Dim streamWriter As StreamWriter

HttpRequest = HttpWebRequest.Create(strUrl)

HttpRequest.Method = WebRequestMethods.Http.Post

HttpRequest.ContentType = "text/xml"

HttpRequest.Timeout = 999999999

HttpRequest.ContentLength = Str(Len(temp))

streamWriter = New StreamWriter(HttpRequest.GetRequestStream)

streamWriter.Write(temp)

streamWriter.Flush()

streamWriter.Close()

HttpRequest.GetRequestStream.Close()

HttpResponse = CType(HttpRequest.GetResponse, HttpWebResponse)

streamReader = New StreamReader(HttpResponse.GetResponseStream)

temp = streamReader.ReadToEnd

streamReader.Close()

HttpResponse.Close()

Please advice on a resolution

Thanks,
Anil

Hi Anil,

The error information means there are some network connection faults. In this situation you need to use try/catch block to handle the exception and set up connection again.
