Help wanted with an old issue

Billy, whilst I don't think the cause of the timeout failure is the same as is mentioned in this code below, but latter the poster claims the timeout is now working, so perhaps the corrected code may assist.

It looks like he is using a different syntax to create the wr object too.

Cheers

Thanks, I'll try that.

You can try to use a ServicePoint Connection, there you can use ServicePoint.MaxIdleTime / ServicePoint.ConnectionLeaseTimeout

Code:: Dim instance As ServicePoint
Dim value As Integer

value = instance.MaxIdleTime

instance.MaxIdleTime = value

Code:: Imports System
Imports System.Net
Imports System.Net.Sockets
Imports System.IO
Imports System.Threading
Public Class ServicePointExample

' Pass in the name of the Web page to retrieve.
Public Shared Sub Main(ByVal args() As String)
Dim page As String
If args Is Nothing OrElse args.Length = 0 OrElse args(0).Length = 0 Then
page = "http://www.contoso.com/default.html"
Else
page = args(0)
End If

Dim request As HttpWebRequest = CType(WebRequest.Create(page), HttpWebRequest)
' Get the service point that handles the request's socket connection.
Dim point As ServicePoint = request.ServicePoint
' Set the receive buffer size on the underlying socket.
point.ReceiveBufferSize = 2048
' Set the connection lease timeout to infinite.
point.ConnectionLeaseTimeout = Timeout.Infinite
' Send the request.
Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
Dim responseStream As Stream = response.GetResponseStream()
Dim s As New StreamReader(responseStream)
' Display the response.
Console.WriteLine(s.ReadToEnd())
responseStream.Close()
response.Close()
End Sub 'Main
End Class

This is regards to an issue that is as old as MC and relates to what happens when a website such as TMDB or TVDB is down.

Here is an example of the code that is used;

Code:: Dim wrGETURL As WebRequest
wrGETURL = WebRequest.Create(url)
Dim thisProxy As New WebProxy("thisproxy", 80)
thisProxy.BypassProxyOnLocal = True
Dim objStream As Stream
objStream = wrGETURL.GetResponse.GetResponseStream()
Dim objReader As New StreamReader(objStream)

page = objReader.ReadToEnd

This works OK most of the time, the problem is when the "url" is not available for some reason. MC stands still until it times out which is way too long, I tried adding the following to the code;

Code:: wrGETURL.Timeout = 5000

The idea being that the webrequest would timeout after 5 seconds, but it has no effect whatsoever
I could create a separate thread for each of these, but it would take a lot of time and code and is in my opinion, a very complicated solution for a simple problem.

Any help would be appreciated.
