256986 Description of the Microsoft Windows Registry



SYMPTOMS
In Microsoft Internet Explorer 6, when an application uses the Windows Internet (WinINet) API to query the status of a response from a server, the application may not respond to the server as expected.



CAUSE
This problem may occur if the first response that the server sends is &quot;100 Continue.&quot; A server sends a &quot;100 Continue&quot; response to indicate that the rest of the request can be sent. The &quot;100 Continue&quot; response is not the server's final response.

However, WinINet sends to the application the first response that it receives from the server. If the server sends a &quot;100 Continue&quot; response, WinINet treats that response as the server's final response and sends the response to the application. The application does not receive the server's next response and therefore cannot respond to the server as expected.
