FIX: You receive a System.ArgumentOutOfRangeException when you call the Read method from an XmlTextReader class in ASP.NET


When you call the Read method from an XmlTextReader class by using the following code:
String m_XmlDocument = "http://localhost/bug/file.xml";
XmlTextReader reader = new XmlTextReader (m_XmlDocument);
you receive the following System.ArgumentOutOfRangeException error message:
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Parameter name: The specified value must be greater than 0.

Note This hotfix cannot be applied on a system that is running the Microsoft .NET Framework 1.1 Service Pack 1.

This exception was a regression from an earlier fix to the XMLDownloadManager class. The problem is caused by the limitation on connections to http://localhost. The default connection limit for http://localhost has changed from 2 to Int32.MaxValue (2,147,483,647). When the XmlDownloadManager class increments the value, the exception occurs.
