AddResponseHeaders

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

BOOL WINAPI * AddResponseHeaders(
  struct _HTTP_FILTER_CONTEXT *pfc,  
  LPSTR lpszHeaders,                 
  LPSTR dwReserved                   
);
 

Parameters

pfc

Points to a HTTP_FILTER_CONTEXT structure

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 may do so by using the AddHeader member of the HTTP_FILTER_SEND_RESPONSE structure.
