Response Header Buffer Callback

Called once before a sequence of pushed header buffers.

int <function name>(IN int aHttpStatusCode, IN const char * aAccumulatedHeadersStr, IN int aAccumulatedHeadersLen);

Return Values

Returns a value of Asynchronous function return values.

General Information

The response header buffer callback is a function created during recording and can be edited according to the needs of your application. It is invoked once for each response to an asynchronous request. Therefore, for each response, the headers are returned once before the body processing.

This callback is invoked while the response headers are being received. Since the response is arriving when this callback is invoked, you can implement the callback to change the asynchronous behavior for the current response.

The callback is not called at all if no response headers have been received. This includes the case of :

• HTTP/0.9 — an all-body request with no headers

Example

The following example illustrates an asynchronous conversation.
