PHTTP_DATA ReadHTTPResponseData	(	STABLISHED_CONNECTION *	conexion,
		PHTTP_DATA	request,
		void *	lock
	)

This function reads an HTTP response stream from the remote webserver.

Parameters:

	conexion	struct returned by GetSocketConnection that includes the information of the remote host and valid socket.
	request	HTTP request that was sent before. This param is needed to resend the request
	lock	mutext used for exclusive access

Returns:

pointer to a HTTP_DATA Struct with the HTTP Response or NULL if the remote host can not be reached.

Here is the call graph for this function:

int SendHTTPRequestData	(	STABLISHED_CONNECTION *	conexion,
		PHTTP_DATA	request
	)

This function sends an HTTP request to the remote webserver. a CONEXION struct with initialized sockets. If the connection was previously initialized that struct will be resused.

Parameters:

	conexion	struct returned by GetSocketConnection that includes the information of the remote host and valid socket.
	request	HTTP request verbs and data to be delivered to the remote HTTP Server

Returns:

If there is no error, 1 is returned.

Note:

This Function only sends data, handling the responses from the HTTP server is done outside.

int StablishConnection

(

STABLISHED_CONNECTION *

connection

)

This function stablishes a connection against a remote host.

Parameters:

connection

CONEXION struct returned by a previous call to GetSocketConnection

Returns:

If the remote connection can be stablished, 1 is returned otherwise, an error is signaled with 0
