SYMPTOMS
When you use Microsoft COM Internet Services (CIS) with a proxy server (such as Microsoft Internet Security and Acceleration (ISA) Server 2000), you may receive a &quot;400: bad request&quot; error message.



CAUSE
CIS sends an extra zero byte after the HTTP CONNECT request. This problem occurs because the proxy server passes this zero byte to the Web server.
