SYMPTOMS

You access Web applications or Web sites from a Web server that uses chunked transfer encoding on a Microsoft Windows Server 2003-based or on a Microsoft Windows XP-based computer. Then, the browser or the Web applications stop responding.

CAUSE

This problem occurs when the Wininet.dll file receives an incomplete chunk of data during the initial Winsock data receive operation. When this behavior occurs, the second Winsock data receive operation reads only a chunk token. For example, the second Winsock data receive operation may only read carriage-return line-feed (CRLF) from the socket. Then, the Wininet.dll file makes continuous calls to the Winsock Select function for 30 seconds. The file is waiting to receive more data. However, if no data arrives, the browser or the Web application stops responding.
