SYMPTOMS
When you use the Microsoft Windows HTTP Services (WinHTTP) on a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based computer to access a Web server over a Secure Sockets Layer (SSL) connection, a memory leak occurs in the process that uses WinHTTP.
CAUSE
This problem occurs if the client uses SSL to connect to a Web server that does not transmit a "server" header to the client request. The problem occurs because of a bug in the Winhttp.dll component.
You may not experience this problem if you use WinHTTP without using an SSL connection.
