HTTP_FILTER_PREPROC_HEADERS Structure

The HTTP_FILTER_PREPROC_HEADERS structure has the following form:

typedef struct _HTTP_FILTER_PREPROC_HEADERS

{
BOOL    (WINAPI * GetHeader) (    
    struct _HTTP_FILTER_CONTEXT *    pfc,
    LPSTR    lpszName,
    LPVOID    lpvBuffer,
    LPDWORD    lpdwSize
    );     
BOOL    (WINAPI * SetHeader) (     
    struct _HTTP_FILTER_CONTEXT *    pfc,
    LPSTR    lpszName,
    LPSTR    lpszValue
    );      
BOOL    (WINAPI * AddHeader) (     
    struct _HTTP_FILTER_CONTEXT *    pfc,
    LPSTR    lpszName,
    LPSTR    lpszValue
    );      
DWORD    dwReserved;     

} HTTP_FILTER_PREPROC_HEADERS, *PHTTP_FILTER_PREPROC_HEADERS;

This structure is pointed to by the pvNotification in CHttpFilter::HttpFilterProc when NotificationType is SF_NOTIFY_PREPROC_HEADERS, which indicates when the server is about to process the client headers.
