Functions
static char *	DecodeChunk (char *lpBuffer, unsigned int encodedlen, unsigned int *decodedlen)
	This function decodes the buffer returned by the remote HTTP Server when "Chunk encoding" is enabled.
int	CBDecodeChunk (int cbType, HTTPHANDLE HTTPHandle, PHTTP_DATA *prequest, PHTTP_DATA *presponse)
	CallBack Function. This function is called from the DoCallBack() function once its registered and will intercept the callback information.

Function Documentation

int CBDecodeChunk	(	int	cbType,
		HTTPHANDLE	HTTPHandle,
		PHTTP_DATA *	prequest,
		PHTTP_DATA *	presponse
	)

CallBack Function. This function is called from the DoCallBack() function once its registered and will intercept the callback information.

Parameters:

	cbType	CallBack Source Type. Valid options are CBTYPE_CLIENT_REQUEST , CBTYPE_CLIENT_RESPONSE , CBTYPE_BROWSER_REQUEST , CBTYPE_SERVER_RESPONSE
	HTTPHandle	HTTP Connection Handle with information about remote target (like ip address, port, ssl, protocol version,...)
	prequest	struct containing all information related to the HTTP Request.
	presponse	struct containing information about http reponse. This parameter could be NULL if the callback type is CBTYPE_CLIENT_REQUEST or CBTYPE_CLIENT_RESPONSE because request was not send yet.

Returns:

the return value CBRET_STATUS_NEXT_CB_CONTINUE indicates that the request (modified or not) its ok. If a registered handler blocks the request then CBRET_STATUS_CANCEL_REQUEST is returned. This value indicates that the response is locked

Note:

This function does not block requests, only tries to decode HTTP response.

static char* DecodeChunk	(	char *	lpBuffer,
		unsigned int	encodedlen,
		unsigned int *	decodedlen
	)			[static]

This function decodes the buffer returned by the remote HTTP Server when "Chunk encoding" is enabled.

Parameters:

	lpBuffer	Buffer returned by the http server (Without headers )
	encodedlen	length of lpBuffer
	decodedlen	length of the returned decoded buffer

Returns:

Pointer to the decoded buffer.

Note:

If the function fails due to malformed or incomplete datachunks, NULL is returned instead. If that happends, the user must use the original lpBuffer data
