FIX: You receive a System.ObjectDisposedException exception when you try to access a Stream object that is returned by the EndGetRequestStream method in the .NET Framework 2.0

SYMPTOMS
Consider the following scenario. In the Microsoft .NET Framework 2.0, you use the BeginGetRequestStream method and the EndGetRequestStream method in the HttpWebRequest class to complete an asynchronous HTTP request. In this scenario, when you try to access the Stream object that is returned by the EndGetRequestStream method, you receive a System.ObjectDisposedException exception.

Note This problem only occurs if you set the Method property in the HttpWebRequest class to a protocol property that uploads data. For example, you set the Method property to POST.
CAUSE
This problem occurs when the Web server resets or closes the connection after the client application sends the HTTP header. The HttpWebRequest class automatically tries to reopen a connection to the Web server to complete the transfer. When the transfer is successful, the EndGetRequestStream method incorrectly returns the Stream object from the first failed connection attempt, instead of the Stream object from the successful connection attempt. When the client application tries to use this disposed Stream object, a System.ObjectDisposedException exception is thrown.
