SetUserCachingKey callback function
Applies to: desktop apps only
The SetUserCachingKey callback function is used by Web filters to set the user caching key. The user caching key is the key that the request will be cached with. This key is used to check if the given request is in the cache, so there is no need to pass the request to the server. The key is also used to cache the server response after it arrives. The URL of the request is used as the default cache key.
The SetUserCachingKey callback function is declared as:
BOOL WINAPI SetUserCachingKey( _In_ struct _HTTP_FILTER_CONTEXT *pfc, _In_ LPSTR lpszCacheKey );
Pointer to the HTTP_FILTER_CONTEXT data structure that is associated with the current, active HTTP session. Pass the filter context in this parameter.
Pointer to a null-terminated string containing the new caching key.
This callback function returns TRUE if the call is successful; otherwise, it returns FALSE. To obtain extended error information, call GetLastError.
