In some cases, there can be requirements to transfer some content arriving through the HTTP transport to an FTP/SFTP location synchronously and then acknowledge the http client with the status of the transfer. This can easily be accomplished with a proxy similar to the following in WSO2 ESB 4.8.x.
Here we use the OUT_ONLY property when calling the VFS endpoint since we are not going to receive a response from it. We use the call mediator to synchronously call it. Also we append retry counts and and reconnection timeouts to the VFS URI to retry transfer in case the endpoint is temporarily unavailable. Finally we build a payload with the status and send it back to the client using respond mediator.
