virtual BOOL GetFilterVersion( PHTTP_FILTER_VERSION pVer );
Return Value
Nonzero if the filter was properly loaded. If the filter returns 0, then the filter application will be unloaded and it will not receive any notifications.
Parameters
pVer
A pointer to the HTTP_FILTER_VERSION structure containing the server’s version information and fields for the filter to indicate version number and notifications. The filter application also includes space to register a small description of itself. The following two flags are set in the structure by the default implementation:
Remarks
This member function is called by the internet server to get the filter version indicated by pVer. It is called only once, after the CHttpFilter object is constructed.
Use dwFlags to specify the notifications in the pVer member that interest your server. Here is a list of the valid flags for dwFlags:
SF_NOTIFY_ORDER_DEFAULT
Loads the filter at the default priority. This value is recommended because other priority notifications can have a strong impact on performance and scalability.
SF_NOTIFY_ORDER_LOW
Loads the filter at low priority.
SF_NOTIFY_ORDER_MEDIUM
Loads the filter at medium priority.
SF_NOTIFY_ORDER_HIGH
Loads the filter at high priority.
SF_NOTIFY_SECURE_PORT
Notifies the application that it is passing data through a secure port.
SF_NOTIFY_NONSECURE_PORT
Notifies the application that it is passing data through a nonsecure port.
Note If you set neither SF_NOTIFY_NONSECURE_PORT nor SF_NOTIFY_SECURE_PORT, the server defaults to both, which allows processing data through any port.
SF_NOTIFY_READ_RAW_DATA
Allows the application to see the raw data. The data returned to the client will contain both headers and data.
SF_NOTIFY_PREPROC_HEADERS
The server has pre-processed the headers.
SF_NOTIFY_AUTHENTICATION
The server is authenticating the client.
SF_NOTIFY_URL_MAP
The server is mapping a logical URL to a physical path.
SF_NOTIFY_SEND_RAW_DATA
The server is sending raw data back to the client.
SF_NOTIFY_LOG
The server is writing information to the server log.
SF_NOTIFY_END_OF_NET_SESSION
The session with the client is ending.
