System.Net.WebException: The operation has timed out Issue

Question

Hi All,

I'm seeing the 'System.Net.WebException: The operation has timed out a System.Net.HttpWebRequest.GetResponse() ' error very often. I had googled and tried several fixes that were suggested, still no luck.

Here is my code.

Dim objStream As System.IO.Stream
Dim objReader As System.IO.StreamReader
Dim objRequest As System.Net.HttpWebRequest
Dim objResponse As System.Net.WebResponse

Try
objRequest = CType(System.Net.WebRequest.Create(sbURL.ToString), System.Net.HttpWebRequest)
          
objRequest.Timeout = TimeOutInMilliseconds

'Fixes tried 1..no luck
objRequest.KeepAlive = False

If Not UserAgent.Equals(String.Empty) Then
    objRequest.UserAgent = UserAgent
End If

'Fixes tried 2..no luck
'Get the service point that handles the request's socket connection.
Dim point As ServicePoint = objRequest.ServicePoint
' Set the receive buffer size on the underlying socket.
point.ReceiveBufferSize = 2048
' Set the connection lease timeout to infinite.
point.ConnectionLeaseTimeout = Timeout.Infinite       
point.ConnectionLimit = 1000

objResponse = objRequest.GetResponse
objStream = objResponse.GetResponseStream
objReader = New System.IO.StreamReader(objStream)
strPageContents = objReader.ReadToEnd
CURRENT_CONTEXT.Trace.Write("Response Contents", strPageContents)
objReader.Close()

'Fixes tried 3..no luck
'make sure the stream and response objects are closed to make sure we free the connection
objStream.Close()
objResponse.Close()         
objRequest.Abort()

Catch ex As Exception
            'adding some more info while logging          
            Throw New Exception("Unable to log to webtrends" & " URL: " & sbURL.ToString, ex)
Finally

If Not objResponse Is Nothing Then
    objResponse = Nothing
End If

If Not objStream Is Nothing Then
     objStream = Nothing
End If

drLogInfo = Nothing
objReader = Nothing
End Try

I have also tried to increase mas connections....no luck there too

<system.net>

  <connectionManagement>

     <add address="*" maxconnection="25" />

  </connectionManagement>

</system.net>

Please let me know what I'm missing.
