SYMPTOMS
Currently, there is no API to detect whether or not a client is connected for ISAPI applications.



RESOLUTION
The HTTP Server Extension request type (dwHSERRequest) in ServerSupportFunction has been extended to include HSE_REQ_IS_CONNECTED, which can be used to detect whether or not a client is connected. The ServerSupportFunction returns TRUE if the client is connected; otherwise, FALSE is returned. A new header file (Httpext.h) is required for developers to use this new feature in writing the ISAPI applications.

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.
