Hi all.
I am trying to build an application that checks for broken URLs
using the System.Net.WebRequest.Create, but I constantly get this
WebException: "The operation has timed-out." Sometimes on 10 out of
50 URLs, sometimes (more often) on 40 out of 50 URLs. I have tried,
among other things, setting
ServicePointManager.DefaultConnectionLimit to 200, increasing the
TimeOut and setting Keep-Alive to false, but nothing seems to solve
the problem.
This is the method I am using in an iteration for about 50 links:
protected string TestLink(string link)
{
try
{
ServicePointManager.DefaultConnectionLimit = 200;
objRequest = (HttpWebRequest)
System.Net.WebRequest.Create(link);
try
{
objResponse = (HttpWebResponse) objRequest.GetResponse();
}
catch(WebException exc)
{
WebExceptionStatus exceptionStatus = exc.Status;
return String.Format("{2}\n WebException, Msg: {0}<br />Status: {1
<br />", exc.Message, exceptionStatus.ToString(), link);
}
finally
{
try
{
objResponse.Close();
}
catch (Exception ex)
{}
}
}
catch(UriFormatException exc)
{
return String.Format("{1}\n UriFormatException: {0}", exc.Message,
link);
}
catch(NotSupportedException exc)
{
return String.Format("{1}\n NotSupportedException: {0}",
exc.Message, link);
}
catch(Exception exc)
{
return String.Format("{1}\n Exception: {0}", exc.Message, link);
}
return String.Format("{0}\n Success: {1} ({2})", link,
objResponse.StatusCode, objResponse.StatusDescription);
}
Can someone tell me where I am going wrong?
I am calling the method from an exe-file on Windows 2000 Server and
Windows XP Professional (same result).
Thanks.
