Send a file to the server specified in SetHTTPHost, for example if requesting http: www.thegamecreators.com/index.php szServerFile should be "index.php". Also allows you to send POST data to the server which can include variables or file data, e.g. "myvar=5&var2=test". This command returns immediately and waits for the server to reply in the background. You can check the status of the reply with GetHTTPResponseReady and when it is ready retrieve the response with GetHTTPResponse. You can check the progress of the upload with GetHTTPFileProgress.
