webservice not able to download the files

[rams.prsk]

Hi All,

Iam using a webservice to downlad the html, audio and video files from the broadcast server and save it in the relay server after creating the folder, but the file is not getting created and also not able to download the files and iam getting Event 1309 warning stating There is an Internal server error(500). Here is the code below and do guide me on the same :

Dim strSaveAsFileNameWithPath As String = ConfigurationManager.AppSettings("FileEncryptFolder") + strFileName
        Const ChunkSize As Integer = 10000
        Dim iStream As System.IO.Stream = Nothing
        Dim iBroadcastStream As System.IO.Stream = Nothing
        'Dim bytesFileChunk As Byte()
        Dim FileSize As Integer = 0
        'Dim Buffer(ChunkSize) As Byte
       
 
        Dim strMutexName As String = strFileName
 
        Dim strProxyURL As String = String.Empty
        Dim iProxyPort As Integer
        Dim sCompanyID As String = context.Request.QueryString("CID")
        Dim BroadcastServerURI As String = ConfigurationManager.AppSettings("BroadcastServerURI") + strFileName + "&CID=" + sCompanyID
        If strSaveAsFileNameWithPath.Contains("[COMPANYID]") Then
            strSaveAsFileNameWithPath = strSaveAsFileNameWithPath.Replace("[COMPANYID]", sCompanyID)
        End If
 
        If Not ConfigurationManager.AppSettings.Item("ProxyURL") Is Nothing Then
            strProxyURL = ConfigurationManager.AppSettings.Item("ProxyURL").ToString.Trim
        End If
        If Not ConfigurationManager.AppSettings.Item("ProxyPort") Is Nothing Then
            iProxyPort = CInt(ConfigurationManager.AppSettings.Item("ProxyPort").ToString.Trim)
        End If
 
        'RelayRemoteFile can create a RACE condition as such use mutex to block subsecutive calls
        Using mutex As New Mutex(False, strMutexName)
            mutex.WaitOne()

 
           'Const ChunkSize As Integer = 10000
            Dim readLen As Integer = 0
            Dim ncAuthorize As NetworkCredential = CredentialCache.DefaultNetworkCredentials 'New NetworkCredential("Username", "Password", "Domain")
            Dim ohttpWebRequest As HttpWebRequest = DirectCast(WebRequest.Create(BroadcastServerURI), HttpWebRequest)
            If (Not String.IsNullOrEmpty(strProxyURL)) Then
                objProxy = New WebProxy(strProxyURL, iProxyPort)
                objProxy.Credentials = CredentialCache.DefaultNetworkCredentials
                ohttpWebRequest.Proxy = objProxy
            End If
 
            ohttpWebRequest.Credentials = ncAuthorize
            Dim ohttpWebResponse As WebResponse = ohttpWebRequest.GetResponse()
            Dim Buffer(ChunkSize) As Byte
            Using responseStream As Stream = ohttpWebResponse.GetResponseStream()
                Using oStream As Stream = File.Create(strSaveAsFileNameWithPath)
                    While True
                        readLen = responseStream.Read(Buffer, 0, Buffer.Length)
                        If readLen = 0 Then Exit While ' EoF
                        oStream.Write(Buffer, 0, readLen)
                    End While
                End Using
            End Using
 
            RelayLocalFile(context, strSaveAsFileNameWithPath)
 
            mutex.ReleaseMutex()
        End Using

Thanks,
