AddResponseHeaders

The AddResponseHeaders callback function specifies a response header for IIS to send to the client.

BOOL WINAPI * AddResponseHeaders(

  PHTTP_FILTER_CONTEXT pfc,

  LPSTR lpszHeaders,      

  LPSTR dwReserved      

);

Parameters

pfc

Points to the HTTP_FILTER_CONTEXT data structure that is associated with the current, active HTTP transaction.

lpszHeaders

Points to a string that contains the headers to add. The string should be in the following format:

header:value\r\n

dwReserved

Reserved for future use. This must be zero.

Remarks

AddResponseHeaders() can be used to add headers for client before the server processes the request, but not during or after HTTP_FILTER_SEND_RESPONSE notification. If you need to add a header when the HTTP_FILTER_SEND_RESPONSE notification occurs, you can do so by using the AddHeader member of the HTTP_FILTER_SEND_RESPONSE structure.
