Allows the client of a bind operation to examine the response headers, optionally, terminate the bind operation, and add HTTP headers to a request before resending the request.
HRESULT OnResponse(
DWORD dwResponseCode, //HTTP response code received
LPCWSTR szResponseHeaders,
//Response headers from the HTTP server
LPCWSTR szRequestHeaders, //HTTP headers provided by the bind
//clients
LPWSTR * pszAdditionalResquestHeaders
//Optional additional HTTP headers
);
The URL moniker calls this method when it has received a response to an HTTP request. If the dwResponseCode indicates a success, the client can examine the response headers and can optionally abort the bind operation. If the dwResponseCode indicates a failure, the client can add HTTP headers to the request before it is sent again.
Note that if multiple clients have registered on the bind context for a given bind operation, more than one of these clients can provide an IHttpNegotiate callback interface. Every client providing this callback receives notifications. Each one is given a chance to add HTTP headers or to abort the HTTP transaction. In such cases, the last client to receive callback notification is the client driving the download operation, and it will dictate the final decision.
