We are using AjaxProxy(FROM http://www.codeproject.com/KB/ajax/ajaxproxy.aspx)

on our web site, but started to notice errors accessing log.txt file.

I found that the file is created by Log class and doesn't have ability to switch it off and error handling.

I've added reading file name from configuration and try/catch block

  public static class Log

    {

        private static StreamWriter logStream;

        private static object lockObject = new object ();

    public static void WriteLine(string msg)

        {

                      string logFileName = ConfigurationExtensions.GetAppSetting("AjaxStreamingProxy.LogFile" ,"");

                      if (logFileName.IsNullOrEmpty())

                            return;

                      try

                     {

                            if (logStream == null )

                           {

                                   lock (lockObject)

                                  {

                                          if (logStream == null )

                                         {

                           logStream = File.AppendText(Path .Combine(AppDomain.CurrentDomain.BaseDirectory, logFileName));

                                         }

                                  }

                           }

                           logStream.WriteLine(msg);

                     }

                      catch (Exception exc)

                     {

                            string ignoredMsg = String .Format("The error occured while logging {0}, but processing will continue.\n {1} ", exc);

                            LoggerHelper.LogEvent(ignoredMsg, MyCategorySource, TraceEventType .Warning, true);

                     }

        }
