HTTP_FILTER_CONTEXT (Windows CE 5.0)
This structure is used by HttpFilterProc to obtain information about the current request. This structure is very similar in function to an ISAPI extension's EXTENSION_CONTROL_BLOCK.
typedef struct _HTTP_FILTER_CONTEXT {DWORDcbSize;DWORDRevision;PVOIDServerContext;DWORDulReserved;BOOLfIsSecurePort;PVOIDpFilterContext;BOOL(WINAPI* GetServerVariable);BOOL(WINAPI* AddResponseHeaders);BOOL(WINAPI* WriteClient);VOID* (WINAPI* AllocMem);BOOL (WINAPI* ServerSupportFunction);} HTTP_FILTER_CONTEXT,*PHTTP_FILTER_CONTEXT;
Members
- cbSize
Size, in bytes, of this structure. - Revision**
Revision level of this structure. - ServerContext**
Reserved for server use. - ulReserved**
Reserved for server use. - fIsSecurePort**
TRUE if the event is over a secure port, and FALSE otherwise. - pFilterContext**
Pointer to any context information that the filter wants to associate with this request. Any memory associated with this request can be safely freed during the SF_NOTIFY_END_OF_NET_SESSION notification. - GetServerVariable**
Pointer to the GetServerVariable (ISAPI Filters) function that retrieves information about the server and this connection. For some notifications, some variables might not be defined. For example, notifications that occur before SF_NOTIFY_PREPROC_HEADERS, such as SF_NOTIFY_READ_RAW_DATA, might not be defined. - AddResponseHeaders**
Pointer to the AddResponseHeaders function that adds a header to the HTTP response. - WriteClient**
Pointer to the WriteClient (ISAPI Filters) function that sends raw data back to the client. - AllocMem**
Pointer to the AllocMem function used to allocate memory. Any memory allocated with this function will automatically be freed when the session ends. - ServerSupportFunction**
Pointer to the ServerSupportFunction (ISAPI Filters) function used to extend the ISAPI filter functions.
