Proxy WebRequest

Hi Guys,

I have maybe 3 POST requests in a piece of code, in each httpwebrequest i have:

vb.net Code:

'// Has proxies been used?
                If (formProxies.listViewProxies.Items.Count > 0) Then
 
                    '// Initialise the random user agent code
                    Dim randomProxy As New Random
 
                    '// Set a variable to store the random proxy
                    Dim randonProxySelected = formProxies.listViewProxies.Items.Item(randomProxy.Next(0, formProxies.listViewProxies.Items.Count))
 
                    '// If it's greater than 0 there are proxies loaded
                    Dim ProxyArray As Array = Split(randonProxySelected.Text, ":")
 
                    'MessageBox.Show(ProxyServer)
                    Dim ProxyServer As String = ProxyArray(0).ToString
                    Dim ProxyPort As Integer = ProxyArray(1).ToString
 
                    '// Setup the proxy
                    .Proxy = New WebProxy("http://" & ProxyServer & ":" & ProxyPort)
 
                End If

Which selects a random proxy from a listview, some of them are hanging, should the same proxy be used on every httpwebrequest in the same piece of code? the way it is now, on every request 3 random proxies are chosen, i'm not sure if that's whats causing the hanging to happen.

thanks for any info guys

Graham
