System.Net.WebException: The underlying connection was closed: An

[Edgar@CCrane]

I have developed a web application using VB.NET 2003 under the .NET 1.1 Framework and along with that application I also included a web service which will be an entry point for a VB.NET application to update certain data in the web site. The problem that we have recently encounted is that at random times it will throw a "System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send." exception. I have read the previous postings and it seems that there is no solution for this bug at this time. Is this correct?

This problem is discussed in the following post:
http://weblogs.asp.net/jan/archive/2004/01/28/63771.aspx

It comes down to overriding the GetWebRequest method of the generated proxy
class.

protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
System.Net.HttpWebRequest webRequest =
(System.Net.HttpWebRequest) base.GetWebRequest(uri);
webRequest.KeepAlive = false;
return webRequest;
}

I had actually read your postings Jan, but it must of been too late in the afternoon because it did not register. This morning I transfered your function into a VB.NET function and here it is for those of you using VB

Protected Overloads Function GetWebRequest(ByVal Uri As Object)
Dim webRequest As System.Net.HttpWebRequest = MyBase.GetWebRequest(Uri)
webRequest.KeepAlive = False
Return webRequest
End Function

Thanks Jan

Can you give some more data about your application ?

Are you using authentication of some sort ?
