What has changed with how the Kadoe Client system communicates with the DVLA?

Previous versions of this software used Electronic Data Interchange (EDI) technology to send enquiries to the DVLA and receive responses from them.  The EDI interface is no longer supported by the DVLA, and is being replaced with a web service interface.  Instead of communicating with an EDI mailbox, Kadoe Client now communicates with a remote web server.  This web server routes your enquiry to the DVLA, waits for the DVLA’s response, and then routes the response data back to you.
