Data Structures

struct _hhandle

This struct is the information used by FHScan to manage HTTP requests. This struct does not manage sockets, however a pointer to an STABLISHED_CONNECTION is provided. For the user point of view, this handle is only a pointer. an user must not tweak data stored in this struct. More...

This function stops the HTTP Core Engine.

Note:: this function is exported but must be called only from the HTTP.cpp and must not be called manually.

PHTTP_DATA DispatchHTTPRequest	(	PHHANDLE	HTTPHandle,
		PHTTP_DATA	request
	)

This function gets an stablished connection against the remote host, sends the generated HTTP the request and Waits for a response. Callbacks are called at this point.

Parameters:

	HTTPHandle	Handle to the remote host.
	request	struct that stores both header and post data that will be delivered to the remote HTTP Host.

Returns:: : returns a PHTTP_DATA struct however, if the remote host can not be reached, NULL is returned instead.

Note:

If the remote host does not return data, and empty struct is returned.

This function shouldnt be called remotely as for example, does not suport authentication. Instead, use SendHTTPRequest() exported at the public interface.

Registered CallBacks are called from this point.

void FreeConnection ( STABLISHED_CONNECTION * connection )

This function is used to clean the status of a connection struct when the conexion socket is closed or when there is a problem reading the HTTP stream (like timeouts).

Parameters:

connection

Pointer to a CONEXION struct

Note:: All the internal counters are reset and the first pipelined request is removed.
If there are pending pipelined requests this function will also reconnect the socket and send those requests to the server

void FreeHTTPData ( HTTP_DATA * data )

This function deallocates the memory of an an HTTP_DATA struct.

Parameters:

data

pointer to an HTTP_DATA struct allocated by a previous call to InitHTTPData().

Note:: This function also tries to match if the assigned memory to HTTP_DATA->Data is a memory mapping. If so, the file mapping will be removed

int HTTPCoreCancelHTTPRequest	(	HTTPHANDLE	HTTPHandle,
		int	what
	)

This function is used to clean the connection struct and cancel I/O request.

Parameters:

	HTTPHandle	Handle of the remote connection.
	what	Cancel only the current request HTTP_REQUEST_CURRENT or blocks all connections against the remote HTTP host with HTTP_REQUEST_ALL.

Note:: This function is needed when for example a CONNECT call is sent against a remote HTTP proxy server.

int InitHTTPApiCore ( void )

This function is used to start the HTTP Core Engine and must be called only once.

Note:

this function is exported but must be called only from HTTP.cpp and must not be called manually.

Under Win32, WSA Sockets are also initialized.

Supported Core Callbacks must be registered here. Example Chunk encoding, gzip compression..

PHTTP_DATA InitHTTPData	(	char *	header,
		char *	postdata
	)

This function Initializes an HTTP_DATA struct with the headers and and data sent or returned by a client or an http server.

Parameters:

	header	pointer to an string that contains HTTP headers. This value can be null
	postdata	pointer to an string that contains HTTP data. This value can be null.

Returns:: pointer to an initialized HTTP_DATA struct.

Note:: if header or postdata is null and empy string will be allocated.

int RemovePipeLineRequest ( STABLISHED_CONNECTION * connection )

This function Adds a pending request struct to the connection pool.

Parameters:

connection

CONEXION struct returned by a previous call to GetSocketConnection. From this connection the first added request struct will be removed (FIFO)

Returns:: This function returns the number of pending pipelined request.
