Hi I have tried sending httprequest as shown in the following using UniHTMLFrame. If I use a gateway the message is sent correctly, however if it sent directly it only sends "Option" issue with Cross-Origin Resource Sharing (CORS). How is possible to overcome this and not use a gateway? Thanks   <script>     var request = new XMLHttpRequest();     var HTTPServerIP = "192.168.1.10";     var HTTPServerPORT = "8765";     var HTTPServerVersion = "V6";
