SF_REQ_GET_CONNID

  • [アーティクル]

In earlier versions of IIS, this support function could be used to retrieve the connection ID of an ISAPI extension, which is contained in the extension's EXTENSION_CONTROL_BLOCK Structure. This value was used to coordinate shared data between ISAPI extensions and filters.

Note

This support function is no longer supported in IIS versions 4.0 and later.

      PHTTP_FILTER_CONTEXT pfc,

      DWORD ul2
);
